Volkswagen Golf GTI under the surface


gti_under_cover_1The first-generation Golf dating from 1974 had been endowed with this uniqueness from its inception. When the number 1 was presented to the press at Munich in May 29 years ago, the original generation already bore the typical features that would immediately make it a bestseller: the dynamic C-pillar resembling the drawn string of a bow, the unequalled variability in the segment at the time, the lively engines and, last but not least, the extremely safe, neutral chassis complete with front-wheel drive were impressive all along the line. The new Golf has all the ingredients to continue in the successful footsteps of its predecessors: a clear plus in terms of dynamics, spaciousness, safety, quality and fascination make it an all-round talent for millions of people from all walks of life.

It is an established fact that the body of the new Golf has increased in size, safety and quality. A major aspect in this respect is the substantial improvement in rigidity. The dynamic rigidity of the body has been increased by 15% in torsion and 35% in flexion; the static torsional rigidity of the body (25,000 Nm/°) has been improved by no less than 80% (!), which is the best value in the segment.

Irrespective of the safety offered, the high level of rigidity does not come at the detriment of the body weight. It has rather been achieved through systematic lightweight construction. Particularly effective lightweight construction measures worth emphasising are the improved join techniques involving laser welding and the optimised layout of the member structure. There has again been a significant increase in the proportion of high-strength body panels used. The net result is a significant plus in terms of body strength, crash safety and comfort whilst optimising weight. For example the laser-welding process: 140 special robots ensure the high body rigidity of the Golf, among other things, by means of laser-welded seams with a total length of 70 metres, as compared to five metres in the predecessor.

gti_under_cover_2The new Golf is essentially characterised by a highly aerodynamic basic body shape. The preconditions for this aerodynamic body shape have been established among other things by defined retreats in the front and rear ends, extremely small shut lines and joint dimensions and the fitting of the windows and headlights flush with the body. In addition, the aerodynamically optimised door mirrors and the trim panels also developed in wind tunnels on the underside of the car make a significant contribution to the drag coefficient of CW = 0.32.

The 2.0 FSI is recommended as the new top-of-the-range engine among the FSI powerplants. This four-valve engine delivers 150 bhp (at 6,000 rpm) and provides remarkably sporty performance. The Golf 2.0 FSI reaches a top speed of 128 mph, accelerates to 60 mph in 8.6 seconds and uses on average just 7.2 litres of fuel–a consumption figure which even a diesel engine would be proud of. The Golf 2.0 FSI comes as standard with a six-speed gearbox. The six-speed automatic gearbox with Tiptronic function is also available as an option to this engine.

gti_under_cover_3To power the generation V Golf GTI, Volkswagen is using a newly developed 2.0 liter FSI turbo engine. The 200 bhp direct injection petrol unit with a high-compression ratio of 10.5:1 makes an ideal GTI engine thanks to its dynamic torque curve (206 lb-ft between 1800 und 5000 rpm). With a standard six-speed gearbox, the four cylinders accelerate the Golf GTI to 62 mph in just 7.2 seconds. The GTI goes from 37 mph to 62 mph in 5th gear in only 7.5 seconds and reaches its maximum at 146 mph. The Euro 4 engine has an average fuel consumption of a frugal 8.0 liters per 100 kilometers. The extremely quick dual clutch gearbox (DSG) for uninterrupted power in gear changes is available as an option. It enables the Golf GTI to charge to 62 mph in 6.9 seconds.

The six-speed manual gearbox features a magnesium selector housing, cable control and very short shifting strokes. A “3-band” synchromesh in the lower gears guarantees maximum shifting comfort. Optimisation of details such as for example reduced-friction smooth-running bearings has helped to further increase gearbox efficiency and further reduce engine fuel consumption. The gearbox has a hydraulic dry single-plate clutch with a vibration-isolating dual-mass flywheel.

gti_under_cover_4The six-speed automatic gearbox (Tiptronic) of the Golf is a real innovation. Up to now Volkswagen has been the only manufacturer in the world to offer a transversally mounted six-speed automatic gearbox at the front in this segment. The shift programs adapt automatically to driving conditions (e.g. driving uphill or towing a trailer). Alternatively, gears can be selected manually by means of a Tiptronic function (+/-). The extremely sporty shift program “S” provides even more agility.

The large effective gearbox spacing results in improved acoustic properties, fuel consumption and acceleration figures in comparison with four- or five-speed automatic gearboxes. The maximum torque capacity of this automatic gearbox is more than 300 Nm. In the interests of easy serviceability, the gearbox is filled with a fluid which does not have to be changed (lifetime fill).

The most innovative gearbox in the world at present is known as DSG or automatic direct shift gearbox. It combines in a fascinating way the comfort of an automatic gearbox with the agility and economy of a manual gearbox. The DSG also has six forward gears. As one of its outstanding design features, the transversally mounted gearbox has two wet clutches (higher thermal load tolerance than dry clutches) with hydraulically regulated pressure. So-called clutch C1 operates the odd gears (plus the reverse) while C2 operates the even gears. This gearbox unit is essentially two gearboxes in one. This substantial level of clutch management is required because there is no longer the typical interruption of tractive force for automatic manual gearboxes when changing gear. An incomparably dynamic and at the same time comfortable gearshift feel is conveyed under conditions of supreme comfort.

gti_under_cover_5In parallel with its fully automatic mode, the DSG has a Tiptronic function, which allows manual gearshifts. Both modes convey a gearshift feel which is characterised by not only absolute comfort but also extreme pleasure when changing gear. Drivers with sporting aspirations experience for the first time that the gears are changed as if by the touch of a button. By recording the wheel speeds via ABS, the gearbox control unit also ensures for example that there are no unwanted upshifts in corners.

Essentially, the engine connected to the DSG always runs in the optimum torque range because every gear generates tractive force immediately. No less crucial is the fact that the new gearbox delivers an extremely high level of agility while maintaining the consumption figures of a manual gearbox. The acceleration and top speed figures are virtually identical.

Golf hatch light upgrade to twin LED modules

The standard lighting in the hatch of the MarkV Golf leaves a lot to be desired, the easiest way to upgrade this is the use of LED modules. The drop in replacement units that replace the standard globe are not going to push out much more in the way of light because of the design of the fitting so I choose to use 2 flat directional 28 LED modules. Installation takes around 60 minutes.

The standard lighting is shown in the photo to the right.

After unpacking the new LED light kit you will have a set of adapters for replacing the standard light, foam to stick the LED light kit to a surface and the LED unit itself.

This unit has 28 LED’s in a 4 x 7 layout. (edit I’ve just replaced the units with a 48 LED unit – see details and photo below – the photos still show the 28 LED module)

The standard globe is around 39mm which is longer then the longest adapter. There are a few options here. You can cut the wiring harness and join the wires on, solder wires to the light fitting or my recommended way is to extend the longest adapter. This is a simple process that involves you carefully using pliers or slip joint  pliers to loosen the ends, once one end comes off mix up some epoxy resin and fill the end and part of the tube and push it back together until you end up with the adapter being the same lenghth as shown in the photo below. The 48 LED module comes with a spring loaded adapter so this isn’t required however I would place some shrink wrap over the outside to minimise any risk of the spring moving and causing a short as this will blow the interior light fuse.

Clip the adapter into the light fitting and fit the light as shown, the double sided tape included is sufficient to hold the module in position but as there is little surface area for it to stick it you need to wipe down the area with a suitable cleaner. You could use a cable tie to ensure it stays in place as you can see in the photo to the left but I found this isn’t required, this can all be done without removing any trim. You can see a wire attached to the harness in this photo which is the power to the other side and also at the right hand edge you can see where the wire passes down from the top behind the trim and down into the trim that runs down beside the hatch opening.

The photo on the right shows the hatch with one of the new LED modules installed, the light is an improvment but there is still a shadow cast by the wheel arch.

To run the cable around to the other side I tucked it in around the trim, you can see the wire sticking out from a few places to give you an idea of how to run it. The left hand side LED module is fitted the same way as the first, get the wire hanging out of the correct location and then fit the module and stick it into position.

That’s it, the install is now finished, all the wires can be tucked away and you should have a result that looks like this (the new 48 LED modules are even brighter and have a slightly warmer colour).

The 48 LED modules are USD $8.28 delivered anywhere in the world from Dealexteme, the new .  The light is also projected out to the ground behind the car providing extra illumination. These LED modules draw ~3.4w (275ma @ 12.45v) each so combined they draw ~6.8w which is ~1.8w more then the single incandescent globe did earlier.

New 48 LED Module

The 28 LED modules are USD $10.84 delivered anywhere in the world from Dealexteme however I ended up with dry joints on both of these in a number of locations, some where from new and some developed soon afterwards so I don’t recommend these any more.

It might be worthwhile fitting a resister when the lights are installed if the lights are operated with the engine running but as I only use my hatch with the car switched off most of the time I didn’t worry about this.

Volkswagen Golf Dictionary

Volkswagen Dictionary (translated from Volkswagen Sweden website originally in Swedish)


An important factor in the development of a body is aerodynamic, because it affects fuel consumption, top speed and volume. In most publications on the cars down, which measure the car’s aerodynamic characteristics, the wind tunnel measured air value (cw value). A number of variables affecting cw-value, including the shape of the bodywork (then, combined or hatchback). Narrow column dimensions and the joints between the exterior body components reduces the eddy formation and favors thus a low air resistance. While the base design is important. Special undercarriage panels in plastic provides a lower air resistance. At the same time protect the undercarriage from stenskott, is lighter than a conventional under-protection and can be easily recycled.

Aero Wipers

Volkswagen aero wipers representing unchanged vindrutetorkarkvalitet even at high speeds.
Compared with conventional wipers working aero wiper blade quieter. Its wiper blade technology is based primarily on how sophisticated the air flow around the streamlined wiper blades. Wiper arm is characterized by its particularly high stiffness and high anliggningskraft against the box without the help of extra components. The noise that may occur no longer exists. Even in heavy rain the driver can continue to enjoy a safe and relaxed driving. For this also contributes the large “sweep the area”. Since torkarbladens rubber worn out more slowly leaves need not be changed as frequently and this in turn means lower maintenance costs. Moreover, aerotorkarbladens basic form, designed so that all the mechanical and aerodynamic requirements of the drying devices are met, even at high speeds. Finally, it is worth mentioning that the kilns of course, has a particular role to play even if it’s not raining, for example, for cleaning of the box.

Airbag System

The central styrdonet for air bags are mounted on ramtunneln the center console and contains sensors to trigger airbags. This actuators detects and evaluates a crash, before it activates the airbags that are justified by the type and strength of the collision. Styrdonet receive information from up to six external acceleration sensors (crash sensors). The central styrdonet for air bags containing sensors to measure the accelerations in length-cross and vertical. It also has a sensor that measures the vehicle’s acceleration around the longitudinal axis. The sensors in styrdonet is to evaluate and compare the signals from other sensors in the car. This allows for styrdonet to estimate the collision direction and strength, and with it the basic right to activate airbags.
Volkswagen’s extensive research and continuous development has refined the governance of schemes so that the protective effect can be optimized for widely different types of collisions. The front airbags for front seat, which is being released in two stages, depending on the strength of the collision, further reduces the risk of injury to the driver and passengers.
The system distinguishes a crash and the strength of a strong shock, caused for example by the car driving on a stone or passing a deep pit in the road.This will ensure that no security system is dissolved without a crash really happened.

Airbags ( “airbags”), together with safety belts reduce the risk of harder head and chest injuries in serious accidents if the crash sensors register a collision, the strength needed to trigger airbags, teeth airbag system a gasgenerator. This, in turn fueling airbags, which are located in the steering wheel and dashboard in front seat passenger, within 30-40 milliseconds. It triggered the air bag protects the head and upper body and the benefits of the resulting crash energy over the widest possible area. Already for 120 milliseconds core is exhausted, so that the air pillow fall apart. By the head and neck movements reduced airbags in cars to help reduce the risk of injury. A further development in the usual air bag is the tvåstegsutlösande front air bag, such as exist in the Volkswagen Phaeton. It has a two-step carefully controlled release of the airbag. But optimal protection can only be tackled if all passengers are on their seat belts, because the air bag together with the belt tensioner which forms a model for balanced security system. In addition to the front krockkuddarna are also side airbags front and rear and sidokrockskydd curtains along the side windows, depending on vehicle model.

Driver and passenger airbag

The purpose of the driver and passenger airbags are they going to protect against head and chest injuries in frontal impacts. Their full effect is achieved only in combination with the seat belt.
While the driver’s airbag is integrated into the padded steering wheel hub is passenger air bag in the instrument panel trim, in the front passenger seat, where the dashboard trim, the special seams that shortcomings, when the air bag deploys. When the electronic trigger system’s sensors detect that a collision with a certain strength has occurred ignite the airbag pyrotechnic gasgenerator. It then suddenly generated gas (usually nitrogen) need to fill air pillow, before the body hits it.
When the head and upper body face into the air pillow pillow may not be a hard barrier to keep its internal pressure. The conflicting body press the gas from the air bag by utsläppshål, so that the person to be protected captured by the soft pillow.
The driver’s airbag is full size ( “full size” format) and contains between 60 and 65 liters of gas, while passenger crash cape has a capacity of up to 150 liters, depending on car size. The passenger air bag can often be disconnected with a key switch, so that a child can be placed safely in the passenger seat. Volkswagen equips all models with krockkuddssystem, whose reliability is always checked in a special control system.

Active safety

Anything that can prevent an accident related to active safety. Among the most important active safety features include:

  • Stability: the results of the chassis design regarding the suspension and kurvstabilitet. That is on the steering precision, braking power and braking stability.
  • The lowest possible burden on the occupants caused by vehicle vibration and noise from the chassis and engine and climate impact.
  • To see and be seen: This is enhanced by good lighting on the vehicle and through good run around with the minimum of dead angle).
  • Ergonomics: This has all Volkswagen models through the logical location of all buttons and levers, for example, lights, windscreen wipers, climate control and radio. These elements must be located in an optimum manner so that they can be reached from the driver’s seat.

A high active safety help drivers cope with dangerous situations, caused due to unpredictable external factors, outside the driver’s control, or by circumstances, as the driver itself inattention creates through.
Many of today’s comfort features also improves active safety. An example is a rain sensor. It relieves the driver and increases comfort during the journey. At the same time improves the visibility of the car, thereby contributing to active safety. Another example is the automatic climate control. The pleasant temperature in the car improved well-being on board, while it becomes easier for the driver to maintain concentration. Tests have shown that when the temperature inside the car is 27 ° C, so the driver missed an average of six percent more visual and acoustic signals than at a temperature of 21 ° C. Along with the passive safety features help the active safety for optimum protection for everyone in the car.


Optimized aerodynamics and good visibility all around requires large and Contracting glass surfaces. Even at small solar radiation than the temperature inside the car. It is access to so much cold air as possible is desirable. For a comfortable temperature level in the car, equivalent to room temperature, requires access to a climate control.

Climate site consists mainly of a cooling system, a heating system, humidity control and a fan. This complements the conventional heating and ventilation system in a car. A climate plant produces no real cold without working for the same principle as the heat pump in a refrigerator.

This creates cold by directing heat away. Put simply run air through the evaporator, where air heat diverted to a cold media. The refrigerated and dry air (humidity possible distilling in the evaporator and spilling out in the car) then blown into the car. A compressor circulates refrigerant in a closed system. After the heat raised by the refrigerant in the evaporator (where the refrigerant simultaneously released in gaseous) pumped refrigerant to the so-called condenser in the front of the car, where the heat emitted by the wind speed and refrigerant returns to the liquid, that is pumped into the evaporator for a new revolution. Some systems, which, for example, Volkswagen Golf, has an externally controlled compressor with an evaporator, which can be set at between 2 and 12 ° C. This ensures that the air is not wiped more than necessary, which would lead to unnecessary energi-/bränsleförbrukning.

Air-conditioning, 2-zone

2-zone climate control, Climatronic, making it possible to set different temperatures for the driver and passenger side. The car’s interior size and luftmunstyckenas placement is crucial to what the maximum temperature difference becomes. In Golf, for example, a temperature difference of 2 ° C between right and left sides achieved.

Air Quality Sensor

Air quality sensors are part of Volkswagen’s “Climatronic” system in the Golf, Jetta, Touran, Eos, Passat, Touareg and Phaeton. Its mission is to measure the environmentally hazardous substances, in the form of oxides only, or reducible gases, in outdoor air. Examples of oxides only gases are carbon monoxide (CO), hydrocarbons (fumes from benzene or petrol) or incompletely burnt hydrocarbons. Reducible gases are nitrogen oxides (NOx). If the quality of outdoor air drops to a critical level, for example at traffic lanes, or when driving through a tunnel, activate the control system “Climatronics” re-circulation function of interior air (the intake of air from outside is suspended and the air in the cockpit allowed to circulate), which prevents outdoor air of poor quality, worsening air quality innen in the car.

Anti lock brake system (ABS)

The anti-lock brakes (ABS system) prevents the wheels låsersig if it slows the car up. If the wheels lock the disappearance of their ability to raise forces sideways, with the result that the car can not be controlled controlled. To this does not happen monitors ABS-styrdonet all wheel speeds, using wheel speed sensors. If one of the wheels tend to lock firmly reduce a solenoid valve in styrdonet for ABS system, brake pressure to the wheel, so that it can rotate freely again. Then increased the pressure again to the limit of blocking.The car remains stable and retains its ability to steer.

In all modern ABS systems, of the type used Volkswagen, repeating the process several times per second. The driver detects when the ABS system works, in the form of a slight pulsation in the pipeline bromspedalen.Inom ABS system of work the car driven without problems, even at maximum braking for away maneuvers and to avoid a collision.

Antispinn control (ASR)

For today’s strong torque engines, contributes antispinn regulation (ASR) for greater comfort and safety, especially when driving on slippery roads or on roads with different grip. Antispinn regulation allows start without wheel spin or lateral movements and smooth acceleration throughout the speed range.

ASR works in conjunction with the electronic throttle (E-gas) and using the anti-lock braking the (ABS) speed sensors. If a wheel suddenly starts to rotate faster than the other (spinning wheel) as ASR intervenes in the engine management and reduces engine power until the wheel stops spinning.
Antispinn regulation contributes to the active safety, in that it helps to maintain the vehicle’s grip and stability at all speeds It also reduces the tire wear.When antispinn regulation is working a tell-tale flashes on the combined instrument. The system also includes an electronic differential locking device (EDS) and is part of the Electronic Stability Program (ESP). ASR can be turned off by pressing the ESP button.


When the ignition key is withdrawn activates the electronic theft protection and prevent, through motorstyrdonet, effectively that the car is started by unauthorized persons. The system uses an ignition key built-in transmitter / receiver (Transponder). This sends any new start-up process a new code to the car’s electronics. Start Blocker lifted only if the key is equivalent eligibility. The system is secure against electronically copied keys by a new type of coding technology.

Please Note: No system can, however, guarantee a 100%-IGT immobilizer.

Bi-Xenon Headlights

Bi-Xenon headlights (bi = two) is a special version of Xenon-headlights, where a single lamp generates both the passing and driving. At dipped covers a moving screen part of the beam trawl. When switching to the beam moving an electro-magnetic protection away from the beam trawl.


The car’s braking system is an important safety component. The more efficient brakes, the shorter the braking distance at a certain speed. The brakes must be matched to the engine performance, vehicle weight and the possible top speed.
For security reasons, modern cars equipped with two brake circuits, which affect the wheels diagonally on the car. On the small and compact models are a combination of disc brakes front and rear drum brakes of the braking power is required.
On models with bigger engines and medium-sized cars use Volkswagen disc brakes both front and rear. The front brake discs are stronger and ventilated.
The braking systems of today’s Volkswagens are among at least anti-lock ABS system, servo brake and electronic brake force distribution (EBF).

Brake Assistant

Brake Assistant, Volkswagen is to help the driver in an emergency or panic braking. With the guidance of how fast the pedal trampled underfoot feel Brake Assistant whether the driver wants a maximum braking and then automatically increases braking pressure, up to ABS rules, so long as the driver keeps the brake pedal depressed. When the driver eases the brake system reduces the braking pressure to the required value.
In this way, the braking distances are reduced sharply. The system works in the near imperceptible to the driver.

Brake Servo (braking power amplifier)

Brake Servo reduces energy a driver must put on the pedal when braking.
A novelty is the two-stage servo brake located in the Gulf. Up to a brake pressure around 45 bar, the so-called comfort-braking zone, working the system with an enhancement factor of 5. Trample driver harder on the brakes increased braking enhancement up to a tenfold value. For the driver, this means quick brake response with short pedalväg, good doserbarhet and reduced power requirements on the brake pedal, up to the point where the ABS begins.



The number of electronic components in cars is increasing all the time. As usual conductors, arranged in a conventional manner in long cable bundles, no longer cope with the volumes of data that needs to be transferred, we use now instead CAN data bus.

The concept of CAN (Controller Area Network) denotes a serial bus system, specially developed for use in cars. CAN-bus data representing digital data between sensors, control components, actuators, actuators, etc., and ensures that multiple actuators can access signals from a particular donor, to use them for control of their connected components.

A special advantage of CAN, in addition to reducing the amount of wiring, is that the rest of the system can continue to function, even if there is failure of one component. In this way, the risk that the system will not work quite considerably reduced. While long common system is controlled now increasingly via CAN-bus and contributes to enhanced safety and comfort in the car. An example is the electrical unladen DIMMER of Golf. Through it notifies the driver just what sort of lighting he / she wishes to have the ignition, but then it is styrdonet supplying the lamps with the electrical energy needed. This technique is used for example. to create “Coming home” function.

CAN-bus divided into three different categories, depending on how often the signals must be repeated and how large volumes of data to be transferred.Drive-sets-CAN-bus transfers including the signals for motor control, växellådsstyrning and ABS-/ESP-enheten. Comfort-CAN-bus responsible data for climate regulation and Infotainment-CAN-bus data for signals from radio with speed-dependent volume control.

Central (with security)

An important comfort and safety are central lock / reading the doors, trunk and tank cover. When the airbag is dissolved in a collision locked all the doors up automatically. Anyone who so desires can make additional comfort-security settings: Auto-lock, automatic locking luggage or safety central locking, which means that all doors and luggage room locks automatically when you reach a speed of> 5 km / h. Safety central no release at the first opening impulse only driver’s door. Only after a further opening impulse locked the other door and trunk up.

With central remote control

Maximum ease of use is guaranteed by the central with remote control, which Volkswagen offers. With the help of a transmitter system that locks and unlocks all the doors, trunk and on certain models including the filler cap. Burglary protection is also strengthened, since it after locking is not possible to use the door lock button. As protection against assaults are contained in the cockpit of a button with which the center can lock / unlock all the doors and trunk. Crash sensor ensures that all doors automatically locked up in the event of a crash, so that all passengers are safe and can quickly get out of the car.


Climatronic regulate internal temperature in the car, according to the set the desired temperature, by automatically adjusting fan speed and luftfördelningsspjällens attitude, so that it becomes a pleasant and as far as possible, draft-free environment in the cockpit, at all operating and weather conditions.

Climatronics electronic control registers interferes factors manipulators, such as solar radiation intensity and the outdoor temperature, and adjust if necessary by adding more or less kalluft.

By that, as in the Gulf, joining styrdonet to the CAN-bus, open up for additional comfort features: The automatic connection of recirculation in the cockpit at the activation of the windscreen washer or iläggning of the hill to prevent unwanted odors from penetrating into the interior. The speed-dependent regulation of the fan speed, with automatic adjustment of the OUTPOURING air temperature, reduce the noise level at low speeds.
With a simple keystroke activates Climatronic defrosterfunktionen at immiga or ice boxes. It means that the whole fan capacity and heat capacity used to blow hot air against the box. If the outside temperature is above 0 C dries cooling the air before it warms up, which reduces imbildning.
This gives everyone who has Climatronic in his Volkswagen increased welfare, increased comfort and increased security. When the temperature is pleasant driver concentration and reaction capabilities reside, and these two are important for safe driving. Moreover, no passengers arrive at the goal tired and sweaty.

To equip a car with Climatronic is also positive for the car second-hand value.

Coming-home-and Leaving-home function

A good comfort advantage may be with lighting the “coming home” / “leaving home”. When you leave the car turns off the passing beam, the downward lighting in the outside rearview mirrors, rear lights and number cooled-off with a lag (coming home), depending on the model, and the lights when the driver unlock the car by remote opening (leaving home). In this way, the car’s outside lights used to illuminate the darkness of the road from the car. In some models may be the time it takes before the lights extinguished be set either via infotainment system or via flight computer. Suggested should be the time to set the match time it takes to go between the house and vehicles.

Comfort opening / closing

When locking and unlocking the car from the driver or passenger side windows can be simultaneously opened or closed. All electrically operated windows (including the electric takluckan) opens and closes when öppnings-/stängnings- button on the remote control is pressed and held down. When the button is released cease opening or closing process immediately. On the react the same way all the boxes on the key inserted into the door lock, turned to upplåsningsläget and kept there. Even in this case the process is interrupted when the key is levied.

Cross winds Compensation

Cross winds compensation allows the electro-assisted steering (EPS) for Volkswagen creates greater comfort and safety. This convenience feature helps the driver of the constant wind or on the road for a long distance leaning to one side. If styrdonet EPS for the record that the driver all the time may “hold on” in the servo steering wheel automatically set itself and compensates for this. That the driver does not need to “keep to the” longer is a relief and a significantly greater comfort.

Cruise Control

Cruise Control is an electronic help system for the regulation of the car’s speed. It gives the driver increased comfort, especially during long trips with constant speed. It also makes it easier to keep the current speed-makers and reduces the risk of driving too fast and hit by fines or the equivalent. The system “store” and keep the speed the driver selected. The driver can temporarily increase or decrease speed manual with a defined value and then have the chance to return to the speed last stored. Farthållarsystemet can be turned off by pressing the “off” button or to be stepped on the brake pedal or coupling.

Please note:
For safety reasons, not the Cruise Control used in dense traffic or in severe road conditions (slipping, wet surface, etc.).see also “Front Scan”.

Diversity Antenna

Diversity antenna offers the best reception quality, which means crystal clear sound when listening to the radio, even in difficult reception conditions. The electromagnetic waves sent from radio and TV transmitters reflected by tall buildings or mountains. Therefore, the antenna not only receive a signal without any reflective parts after a lag, which can degrade the quality of reception. This is known as multi-tract disorder (multi-path). With diversity antenna, it is up to four antennas, which picks up the radio signal. Thanks to signals from the antennas are linked together in an ingenious manner, the recipient can filter out much of the signal disruption.

DSG gearbox –

The latest innovation at Volkswagen gearbox-development-DSG gearbox, which debuted for 2002 in the Golf R32.
This fully automatic six-shifted gearbox is distinguished by the bills without any driving force interruption. This makes Exchange soft and barely noticeable to the occupants.
-DSG gearbox is basically a manual gearbox, which will be automatically exchanged with two våtlamellkopplingar, which through two input shafts in the gearbox maneuvering gears 1, 3, 5 and reverse (link 1) and gears 2, 4 and 6 (link 2). In an exchange control is the next step already preselected gear mechanically, but not yet plugged.
It takes only three to four hundredths of seconds for a link to open up while the other during the same period is concluded. In this way paging operation is performed without the driver noticing, and without any driving force interruption.

The intelligent control technology and the absence of a power-consuming torque converter, a fuel savings of up to 10 per cent achieved, compared with a sexväxlad manual box, but the saving of course, vary depending on driving. The driver can operate the DSG-box manually or automatically. In the automatic mode, you can choose between the well-balanced and comfortable standard setting or the more stressed sports program. Manual switching is possible, either by paddles or buttons on the steering wheel or the gear selector.

Early Crash sensors

An intelligent system of sensors respond in the event of a collision, for systems with air bags and seat belts are triggered in the most efficient way, taking into account the nature of the collision. With the help of two satellite sensors can sensor system is already in an early identification process and the strength of a frontal impact.
These sensors measure the acceleration, and because they are placed in the car’s front crumple zones known as the “early crash sensors.” The sensors provide styrdonet with signals, so that it can soon discover how serious the impact will be.
As additional information for evaluating the strength of the collision and the plausibility checks the data on the car’s brakes, which are recorded centrally in styrdonet.

Electro-mechanical power steering

The electromechanical power steering is an electrical, power steering with speed-dependent servo effect (servotronic), which is activated only when needed and working completely without hydraulic components. The advantage compared with a hydraulic power steering is that cars equipped with electro-mechanical steering consume less fuel, while offering new comfort and security features: Active recovery of the steering wheel to its neutral position improves steering feeling around the neutral point, wind compensation helps the driver when driving in cross winds or when driving on a path that is tilted sideways. It is for each car’s engine and equipment personalized steering force supplements also contributes to an outstanding handling and feedback. These extra features have been able to be, thanks to styrdonet connected to the CAN data bus.
In many of the Volkswagen passenger car models included electro-mechanical steering in the standard equipment. Electromechanical power steering reduces the cars fuel consumption by 0.2l/100km.

Electronic brake force distribution (EBF)

In all the cars shifted the focus forward in braking. This raises the risk that the rear wheels can be locked, because of reduced pressure on the roadway. The electronic brake force distribution using solenoid valves in the ABS device to regulate the braking force on the rear wheels, so as to ensure maximum braking force both front and rear axle, while under normal circumstances to avoid “over the brake” on the rear wheels causes that bakvagnen “release” grip.
Electronic braking force distribution is part of the ABS function. The electronic braking advantage’s work ends where the ABS-regulation begins.

Electronic differential lock (EDS)

The electronic differential locking device enables a smooth and comfortable start to the road surface with varying approaches. If one of the wheels on one axle starts to spin, knows this system via the ABS system’s speed sensors, and the brakes when the wheels of the car’s brakes and looks that way to more force is headed to the wheels that have better grip.

The electronic differential locking device reduces tire wear and is active up to a speed of 40 km / h (4MOTION: up to 80 km / h). EDS is part of the Electronic Stability Program (ESP) and antispinn regulation (ASR).

Electronic immobilizer

Start Blocker is an electronic immobilizers. It is activated when the ignition key is levied, and together with motorstyrdonet that prevents the vehicle is started by any unauthorized person. The system uses an ignition key built-in transmitter / receiver (transponder). Each time a new attempt is made to start the engine sends a new transponder code to the car’s electronics. Unblocking only if the key is the correct jurisdiction code. A new coding technology ensures that system to electronically copied keys.

Please note:
No system can guarantee 100 percent protection against theft. Thieves with enough skill and determination can be isolated in exceptional cases even outwit the electronic vehicle immobilizer.

Electronic Stability Program (ESP)

The Electronic Stability Program (ESP) recognizes critical driving situations, for example, if there is a risk that the vehicle can get cable, and prevent such situations arise. For the electronic stability program to react to critical situations, the system must be informed.

Examples of such information is: Which direction the driver against the steering and which direction the car is moving towards. The answer to the first of these questions is provided by steering angle sensor on the steering column and ABS speed sensors on the wheels. From the information from these two estimates styrdonet every driver is on the road and every car is on the way. Other important data is the rate of turn and the car’s lateral acceleration. With the help of all this information calculates styrdonet vehicle’s actual condition.

The electronic stability program prevents the car from becoming unstable at kurvkörning. Instability can be caused by excessive speed, surface (water, ice, dirt) or because the driver is forced to make a hasty evasive. The system takes proper action, whether instability is due to understyrning, which means that the vehicle skid outward in a curve or over-steering, which in turn means that the rear of the vehicle starts SKID outwards. The computer in the electronic stability program takes corrections by interfering in the braking system and engine management. At understyrning reduces the electronic stability program, the speed of the rear wheel of the inner curve, while it reduces engine power, until the vehicle’s stability has been restored. It may be similar to the correction of how a terrain controlled: If you want to swing to the right, slowing down the right band and vice versa. If you want to force the car more to the right in a right curve slowed right rear wheels allowing the car driven to the right. The electronic stability program prevents over control (cable) by gently slow down the front wheel in the outer curve and through interventions in the engine and växellådsstyrningen.

Please note:
The electronic stability program can not overcome the laws of nature. If the driver exceeds the limits, as both the chassis and the Electronic Stability Program requires, can not even ESP prevent an accident.


Euro NCAP (The European New Car Assessment Program = program for the evaluation of the passive safety of new vehicles) are considered to be an important measure of passive safety in vehicles. They are even stricter requirements on offset crash tests than those, since October 1998, current EU rules. Collision rate increased from 56 km / h (law) to 64 km / h (Euro NCAP) which represents an increase of more than 30 percent of crash energy. Among the organizers of the Euro NCAP is the British and Swedish road works, the International Automobile Federation (FIA), German ADAC (automobile clubs) as well as other European automobile clubs.


At certain types of accidents can be the driver’s legs exposed to greater harm. To reduce this loss to Volkswagen in particular deformationselement the pedal set and footrests. The deformation of the forward torpedo the wall resulting in Euro NCAP’s krocktest leads, for example, from a well-defined force level, to a deliberate decoupling pedals, so that their intrusion into the cockpit is reduced and so that they remain mobile and does not transfer any forces. This reduces the risk of damage to the feet and lower legs.

FSI (Fuel Stratified Injection)

FSI (Fuel Stratified Injection). FSI is Volkswagen’s name on the engines with gasoline direct injection. In conventional petrol engines, fuel is injected into the intake manifold before the intake valves. With gasoline direct injection gasoline instead injected directly into the combustion chamber with a maximum pressure of 150 bar. A special burning room geometry ensures optimum swirl formation in the gasoline / air mixture. One of the advantages of this is that the fuel cools the combustion engine rooms and that therefore may have a higher compression ratio without risk of knocking. Volkswagen’s innovative engine technology FSI ® stands out for its high effectiveness and efficiency, which is above genomsittet. Compared to other engines of the same capacity and conventional injection technology FSI provides both performance as consumption benefits.

Galvanized body

The safest method to protect steel from corrosion are zinc coating. At the zinc coating produces not zinket a loose layer on top of the plate, but it reacts to the plate and create a stable composition also is insensitive to ytskador.

Zinc coating, applied in very thin layers of less than 20 micrometers (millionth of a millimeter), may be primarily used to treat all the finer surfaces. Zinc coating is applied when the plate is manufactured and is not made afterwards. For technical reasons, helförzinkning not applied in full when the car containing high-strength steel unit.
The galvanized and helförzinkade bodywork has substantial economic benefits, because it ensures the car’s safety, value and integrity for a long time. Zinc coating ensures optimum protection against corrosion and provide bilstrukturens stability throughout the life cycle. The car’s longer life means reduced resource use. Volkswagen offers for many of its models provide an twelve-year-old guarantee against by roasting.

GTI (Gran Tourisme Injection)

In 1976, two years after the launch of the first Gulf, based Volkswagen, with the introduction of the first Golf GTI (Gran Tourisme Injection) class of compact sports cars.

Originally, the GTI was only planned as a limited special series, but because of the enormous popularity, it became a permanent member of the Volkswagen family. “From the” GTI: n performed 110 hp from an engine capacity of 1.6 liters and reached 100 km / h in 9.2 seconds, performance figures at the time was in a class of its own.
The mixture of driving pleasure, functionality and suitability for everyday use filled a gap in the market, and this created GTI-legend. With its new Golf GTI Volkswagen has caught the forces of the first GTI: n and offers with it, thanks to modern engine and chassis technology, driving pleasure without compromise.


With the exhaust-driven turbocharger compressor increases fresh air temperature, when the air is compressed in the compressor. Since hot air takes up more space than cold, the cylinders are filled with small quantity (mass) air than the equivalent boost, and the gasoline engine is increased when the risk of knocking. In order to prevent it cools the compressed air to the engine coolant, or by wind speed, in one or more Intercooler. Charge cooling reduces the thermal load on the engine, while the temperature, nitrogen oxide (NOx) emissions and fuel consumption is reduced.

Interior lights with LEDs

Interior lighting of the internal rearview mirror depending on the model and performance enhancing safety and comfort.The glare-free lighting from two red LEDs help drivers to orient themselves safely in the dark interior compartment during flight and to quickly find and properly set the essential functions.

ISOFIX mounts

ISOFIX is the result of some well-known car manufacturers’ efforts to create a uniform and optimal standard for attachment of the child. ISOFIX child-are equipped with a simplified attachment device. They can be fitted in all cars, that the design was prepared with standard fasteners.

In preparation for the ISOFIX attachment includes two loops, fixed in the body.
Baby seats adapted for ISOFIX anchored in the attachment loops with two arms. ISOFIX-child are easy to mount and the stable fitting into the body offers maximum security.

LED technology

An LED (Light Emitting Diode) is a light-emitting semiconductors, which have a significantly longer life and lower power consumption than conventional bulbs. The benefits of LED technology compared to conventional bulbs, except that the lower energy consumption and longer life, also a faster response time and a more compact design. Volkswagen uses LED above the rear lights and the indicator lights in the exterior rear-view houses.

Thanks to LED technology, short response time is perceived LEDs speed of road users. If a driver can see the front of the car’s previous stop, it may help to reduce braking distance by about 5.5 m at a speed of 100 km / h (other conditions were the same). The high operational reliability and long lifetime of LED increases safety, thanks to reduced risk for the taillight and stop to stop working.

Long Life-oil

The oil in a combustion engine to be responsible for lubrication of engine components and for the removal of the residues arising from burning. Oil quality depends on how the crude oil refined and the additives (additive) to which the oil. Due to the high technical requirements are currently used are often part-or fully oils. They long for service and maintenance intervals for the Volkswagen cars involves the use of such fully engine oils of “Long Life”-type.Depending on the engine and model variant can service and oil change intervals now extend up to 30 000 km or a maximum of 2 years for gasoline engines.

Volkswagen has released 58 different motor oils, which meet the standard 503.00 for gasoline engines and 506.00 for diesel engines, in both cases with extended inspection intervals.
A further 22 oils are released under the Volkswagen 503.01 standard for turbocharged gasoline engines.
For diesel engines, which work with pumpinsprutarteknik is 10 lubricating approved in accordance with the standard 506.01. Cars with long life oils can not be filled after anyway. See the car’s manual for more information.

Passive safety

With Passive safety refers to all the constructive measures taken to protect the occupants of a car from accidents and to reduce the risk of injury in accidents. The term is aimed specifically at the operation of the vehicle in a collision (krocktest), and not just on the protection of the private car, but also on how road-users are protected (Protection). To the main equipment for passive safety in today’s cars, in addition to seat belts with their seatbelt pretensioners, include an air bag, the deformations against resistant interior compartment and crumple zones front and rear. These create significant protection for the occupants to lead off the crash energy. Together with measures for active safety, all Volkswagen models offer a unique “all-round” protection.

Rain Sensor

At intervals drying governing Volkswagen rain sensor, automatic windscreen operating frequency with respect to the intensity of the rain. The sensor is mounted in the bracket for the interior rear-view mirror, and it consists of a number of infrared LEDs and a centrally placed photodiode. The light emitted by the LEDs is reflected by the windscreen against photo sensor. The more water droplets found on the windshield, the less light sensor may receive. This information is forwarded to the rules of electronics, which matches the windscreen operating frequency in the light of this. The sensor’s sensitivity can be adjusted individually with a tilt of the wiper lever. The sensor is designed so that neither minor damage, dirt or aging affects the function of the windshield.
Comfort and safety are the obvious benefits of this rain sensor. The driver can concentrate entirely on what happens in traffic and need not worry about adapting the wiper regulation. This is a great advantage in terms of safety, especially when suddenly emerging obstacles, such as. at overtaking by trucks on wet roads.

Repair Kindness

Repair Kindness is a criterion for body-quality, which optimizes Volkswagen already at the design stage. Crucial to this capacity is how many and which components are injured when a certain type of collision, how quickly the damage can be repaired and how high material costs will be.

Repair kindness is of great importance to a car’s maintenance costs in two ways: first, because it takes into account both the spare parts prices and labor costs, and secondly because it is used for the calculation of insurance premiums for the car.
A good example is the new door module for Golf, which now for the first time used in car manufacturing in large batches. When damage to the outer door plate, which can not be repaired, need now is not the door replaced in its entirety, but it assembles simply a new exterior sheet metal on the otherwise perfectly usable structure. Fösterhissar and door locks are in this way also easier to access, so that they can be controlled directly on the spot.

Safety Pedals

Safety pedals is to reduce the risk of damage to the driver in a frontal collision. A calculated deformation causes the brake and clutch pedal intrusion into the footwell limited to a frontal collision. A hävarmsmekanism disconnect the pedals or steering them to one side.


A bälteskraftbegränsare declining, from a certain limit, the power of the belt which keeps the passenger seat and reduces, in conjunction with seat belt pre-tensioners and air bags, thus the risk of damage to the upper body of passengers.
To create this restriction exists in bältesupprullaren a torsionsstav, which limits the power to the belt at a certain, predetermined force level. The maximum belt force is reduced in this way, and the passengers caught up in a softer way of safety belt and airbag.

Seatbelt pretensioners

Safety belt to tighten around the passengers as quickly as possible in the event of a collision, and therefore have the seat belt held stretched. Because both of the passengers’ clothes and the retraction mechanism is not always possible. It may be simply a loose contact seat belt. The pyrotechnic-triggered belt tensioning will compensate for this by at a distance collision belt.

Split belt will usually triggered by a gasgenerator via krockkuddarnas actuators, but at a lower threshold than the trigger for the front airbags. It means that the belt tensioner can be triggered in a crash, although this is not sufficiently serious to trigger airbags. At the trigger, the belt tensioning is the belt, so this is well stretched against the body. The firm stretching slowed up so quickly, which means that forces have time to spread more evenly throughout the slowdown cycle and reduces the risk of damage to person.

Speed Depending stereo volume adjustment

Speed Depending volume adjustment is a function of the receiver, which adjusts audio reproduction to the current vehicle speed, so that passengers get an impression that the music always played on the same volume. To achieve this, we have been either closed radio system interface to the CAN-bus or use is hastighetsmätarsignalen. With knowledge of the car’s speed regulating system volume, with regard to this.

Sport-leather steering wheel with Tiptronic-swap

This is the sporty alternative to the Multi mode dial.
With this may be the driver, with the swap puffs or buttons directly on the sports steering wheel, affect the power transfer via automatic gearbox. This provides greater driving pleasure and enables personalized, dynamic driving. Treekrade wheel design underlines the sporty character.
An airbag is built into the steering wheel.

Sports Seat

Volkswagen sportstolar security enhancements in the car and convinces with its high its comfort and its attractive appearance. The clear side-payments account for good retention in the chair at kurvkörning and gives the driver more secure control of the car in extreme situations.

Sliding Protection

With the sliding protection (Anti Submarining) meant upward Contracting ramp, located in front of the chair. This device prevents the person sitting in the seat in a collision slides forward or under the seat belt. All Volkswagen chairs / seats are steel reinforced ramps, which reduces the risk of damage in a collision, by preventing the body from the bottom to “dive” below the belt.

The bumper of laissez material (reversible)

The bumper of laissez material is also called reversible stötfågare. They can do without damage from minor bumps up to a speed of 4 km / h.

Plastic material in the bumpers are designed to dents, for example, are caused by weak poles, flower urns or similar objects, automatically springs back, without causing any major repairs. Protective strips, which protect against scratches, adorn many of our models, and attached with clips on the bumpers. Protection lists are cheap and easy to replace, and they contribute to reduced maintenance costs.

Traffic Radio messages / Traffic Message Channel (TMC)

Radio channel for traffic messages (TMC) is a digital information channel for traffic messages, which have constant access to current information about how traffic “flowing”. Volkswagen’s navigation system with dynamic control against the target use of this information (where available) and check, for a pre-selected travel route, the traffic situation around. 200 km ahead of the planned direction and, above all, how traffic flows.
If the TMC system reports that the queues or other traffic barriers are available on the planned route, count it automatically forward an alternative route, and also changes the instructions for steering towards the target, without driver intervention. The navigation system also takes into account the extra driving time as the detour leads, and the detour takes longer than the time it is expected to take to get through sex / past the obstacle is no diversion.

The transfer of information in the same way in the TMC system is now available also in large parts of Europe. Data transmission is digital and independent of language. The appearance is in the language of the user opted for the system.

Tyre pressure

The system for tire pressure monitoring system uses ABS wheel speed signals. If the pressure in a tire is reduced, this will also reduce tire rolling radius, so that the wheel rotates faster for a given speed.
The system helps the driver to keep control on the pressure in the tires.
Such permanent control means increased security. If you always have the right pressure in the tires increased tire life, while fuel consumption is reduced.

Please note!
The system for tire pressure monitoring does not exempt the driver from the responsibility to keep the right pressure in the tires.

Under Floor Panels

Instead of the classic under-reading Volkswagen has increasingly begun to use special protective panels of plastic to cover the floor. This is an effective protection against stenskott. It’s easy, can be easily recycled and are therefore better for the environment.
Moreover improve those under floor panels, body flow characteristics, so that the reduced air resistance, which in turn leads to reduced fuel consumption

Volkswagen Golf 1kg and 2.5kg Fire Extinguisher Installation

Option 1 – Installing in hatch area

Installing a 2.5kg fire extinguisher into the Golf is pretty straight forward, especially with Australian specification cars which don’t have a first aid kit or warning triangle installed. Cars with these fitted will need to relocate them.

First pick out a suitable extinguisher, make sure that it has a brass head as a plastic one can break easily and the resulting mess in your car will be very difficult to clean up. Also choose a metal bracket as the plastic ones are not suitable for car use.

The extinguisher I used is a Flamestop 2.5kg purchased online from a medical supplies company for around AUD$70 delivered.

Remove the existing first aid kit/warning bracket.

There is a bit of a dip in the side where the screw mount is to take note of. There is nothing behind the screw mount is so you can use a reasonable length screw.

On the extinguisher I used the metal band is riveted to where I want to put the screw through so drill it out carefully (rivet is aluminum so this is easy).

Bracket with rivet removed.

Because of the dip in the panel where the screw goes in you need to pack this out a little, keep it a fraction below the surrounding height to keep pressure on the bracket to stop movement. I used a 32mm x 10g stainless screw.

Bracket Installed

Fire Extinguisher installed. I’ve added some silicon around the handle to stop any rattles as there was a little bit of movement in that area.


Option 2 – Installing under front seat

6 – Retaining Bracket – 1K0 881 286 A (1K0881286A) – USD$59.50
7 – 3 x Pop Rivet (6 X 10 X 11.4 mm) – N 908 123 02 (N90812302) – USD $1.10 ea
8 – Holder for Fire Extinguisher – 1K0 882 607 A (1K0882607A) – USD $75.00
9 – 2 x Socket Head Bolt with Inner Multipoint Head (M6 x 20.5) – N 908 973 08 (N90897308) – USD$3.60 ea
10 – Fire Extinguisher 1.0kg – 3D0 860 277 (3D0860277) – USD $380 (special order euro part)


Upgrade Golf Headlights to Osram Nightbreaker

Upgrading to the Osram Night Breaker +90 in the Golf makes a reasonable difference to the throw of the lights and a substantial difference to the colour.

Osram Nightbreaker
Osram Nightbreaker H7

Osram claim up to 90% more light and up to 10% whiter light which from what I can see is pretty accurate.

The standard globes fitted to the Golf were reasonable but could certainly be improved, I would recommend taking optional bi-xenon lights where possible but unfortunately in my case I ended up having to settle for a car without them or face an additional 3-4 months delay.

It’s hard to show the difference the light makes in photos but you can see the difference in output and throw clearly when you’ve changed one globe. The comparative picture from Osram shows the difference between standard and the Nightbreaker +90’s.

Overall I would estimate the additional output/throw to increase the distance from which you can see to be around 20%.

These globes were purchased from Powerbulbs who offer free shipping worldwide.

At the same time I fitted the Philips BlueVision W5W globes to replace the parking lights which were quite yellow looking. These were included free with the order from Powerbulbs and make a big difference.
