Enabling static cornering lights in the Volkswagen Golf Mark VI with factory fitted fog lights

Enabling static cornering lights in the Volkswagen Golf Mark VI (Mark V is covered here) only requires a few changes via Vagcom/VCDS.

The cornering function works when your headlights are activated (either manually or via the RLS) under the following conditions

  • The indicator is activated either by holding it down or clicking it into position (not when comfort indicating)
  • The car is in P, N, D, S or Manual (not when in reverse)
  • The steering wheel is turned 85° from the straight ahead position.
  • The speed is under 50kph (once the car drops below this speed the light will activate and once it goes above this speed the light will fade off)

The fog light on the side of the car that the wheel is turned towards will light up, depending on the speed of the steering wheel the light will either fade in slowly or turn on instantly but the light will always fade out slowly.

You will need a 30 Byte Central Electronics Convenience Module (CECM) which are fitted to MY08’s models onwards.

Open Controller 9 and select Coding – 07

volkswagen_golf_mark_vi_enabling_cornering_lights_01

Click the Long Coding Helper, do not copy down the coding seen as these are specific to each car and it’s options/setup.

volkswagen_golf_mark_vi_enabling_cornering_lights_02

Select Byte 14 and bit 7 – cornering lights via front fogs active.

volkswagen_golf_mark_vi_enabling_cornering_lights_03

Select Byte 17 and bit 0 – adaptive light/cornering light variant (0=cornering light/1=adaptive light) and bit 4 – assistance driving light (auto mode)

volkswagen_golf_mark_vi_enabling_cornering_lights_04

Select “Do It!” to save the coding.

Adding Door Warning Lights to the Volkswagen Golf and Jetta – Front

This guide covers the installation of the door warning lights to the Volkswagen Golf and Jetta front doors as was fitted to the very first Mark V’s before they were discontinued for I assume cost reasons.  Along with the Puddle Lights these really light up the area around the side of the car and Volkswagen really did the owners a disservice by discontinuing these.

The light operates every time the door is opened day or night but it does shut down after the door is open for a period of time.

volkswagen_golf_door_warnng_light_finished_01 volkswagen_golf_door_warnng_light_finished_02

The white light visible on the other side of the door is the Puddle Lights mod which I performed at the same time.

volkswagen_golf_door_warnng_light_finished_03

Parts required:

  • 1K0 947 411 A (1K0947411A) – Door Warning Light (1 per door)
  • 1J0 971 972 (1J0971972) – Connector Housing (1 per door)
  • 000 979 019 (000979019) – Repair Wire for Connector Housing (1 per door – 2 connectors)
  • 000 979 009 (000979009) – Repair Wire (1 required for 2 doors or 1 required per door – see below)
    As you will see in the guide below I only had one end of a  000 979 009 (000979009) – Repair Wire left and took my ground from a nearby connector, I strongly recommend you take the easier approach and take the ground from the controller as it’s quicker and doesn’t require interfering with the stock harness. I have detailed how to do it this way as well in the guide.
  • Interior fabric adhesive tape – Fabric Adhesive Tape for wiring looms and harnesses
  • Trim Removal Tools
  • Selection of heat shrink tubing (3-5mm), soldering iron/blowtorch, solder
  • Vagcom/VCDS to code the door (this can be done before or after the install)

Volkswagen Golf & Jetta Door Controller Information Mark V has information on the door controllers. This guide was based on the install in my March 2008 build MY08 GTI.

The original reflector installed (left) and the  new warning light (right), installation is simple, unclip the old light by pulling it towards you from underneath and clip the new one in.

volkswagen_golf_door_warnng_light_installed_01 volkswagen_golf_door_warnng_light_installed_02

The view from underneath the door, red light is visible and white light is projected onto the area below the door.

volkswagen_golf_door_warnng_light_installed_03

First remove the door trim – Drivers Front Door Trim – Removal and Installation or  Passengers Front Door Trim – Removal and Installation and lay the door trim down on a work surface.

Plug both ends of the 000 979 019 (000979019) – Repair Wire into the 1J0 971 972 (1J0971972) – Connector Housing as shown and lay the cable out along the route that cable will run.

volkswagen_golf_door_warnng_light_installation_01

Using some side cutters remove the cable tie from the rear of the connector housing.

volkswagen_golf_door_warnng_light_installation_02

Using a small screwdriver, your fingernail or any other sharp tool to lever the release and at the same time pull the connector housing away from the housing.

volkswagen_golf_door_warnng_light_installation_03

Connect the end of the 000 979 009 (000979009) – Repair Wire into location 18 on the housing. If you are taking the ground from here as recommended above you will need to install the other end into location 19. The numbering on this side is from 17 to 32.

Please note these pins are for MY07 cars and later, earlier cars have a Gen 1 or Gen 2 controller and this uses pin 1 instead of 18. To tell them apart a Gen 1 or Gen 2 controller will have have the pin 1 location vacant and on a Gen 3 controller pin 1 will be driving the door LED. I’m not sure at what location is a spare ground. See the Volkswagen Golf & Jetta Door Controller Information Mark V page for more information.

volkswagen_golf_door_warnng_light_installation_04

Route the repair wire(s) down the harness running them through the two labels stuck to the harness. If you are running the two wires as recommended you may need to extend one of them, don’t cut the repair wires until you work out what lengths you require, better to extend one cable than two.

volkswagen_golf_door_warnng_light_installation_05

Wrap the wire(s) to the harness with interior fabric adhesive tape.

volkswagen_golf_door_warnng_light_installation_06

Pin 1 which is to the left on the photo should be ground and pin 2 to the right is positive. There is a zener diode fitted inside the lamp housing and if you wire it up incorrectly it won’t work until you reverse the pins or reverse the zener diode. Fit a suitable piece of heat shrink tubing, strip the wire from pin 18 from the controller and the wire from pin 2 on the lamp, twist them together and solder.

If you are taking the ground from a nearby connector skip the next instruction.

If you are taking the ground from the 32 pin connector as recommended strip the wire from pin 19 and the wire from pin 1 on the lamp, twist them together and solder without forgetting to put heat shrink tubing on prior to joining.

Please note these pins are for MY07 cars and later, earlier cars used different pins. See the Volkswagen Golf & Jetta Door Controller Information Mark V page for more information.

volkswagen_golf_door_warnng_light_installation_07

Bend the soldered joint backwards

volkswagen_golf_door_warnng_light_installation_08

Pull the heat shrink tubing over the soldered connector and heat to shrink the tubing.

volkswagen_golf_door_warnng_light_installation_09 volkswagen_golf_door_warnng_light_installation_10

If you’re taking the ground from a nearby connector press the tab as shown to the right and pull the connector from the bottom of the fuel flap switch (this only applies to the drivers door – there are similar grounds on the door switch, pin 21 of the controller, pin 18 of the controller and so forth).

volkswagen_golf_door_warnng_light_installation_11

Open the connector housing by levering it towards the front (the part that is sticking up towards the middle of the connector)

volkswagen_golf_door_warnng_light_installation_12

Push down with a suitable tool to release the pin, pull backwards at the same time on the brown/white wire as you are depressing the pin.

volkswagen_golf_door_warnng_light_installation_13

Bare the insulation from the wire without cutting.

volkswagen_golf_door_warnng_light_installation_14

The result should look something like this.

volkswagen_golf_door_warnng_light_installation_15

Twist the repair wire over the uncovered wire.

volkswagen_golf_door_warnng_light_installation_16

Solder the two together (I use a small gas torch as I get instant heat and don’t have to wait around for it to warm up but sometimes you end up burning the ends of the insulation).

volkswagen_golf_door_warnng_light_installation_17

Cover the soldering with heat shrink tubing and heat that to shrink it.

volkswagen_golf_door_warnng_light_installation_18 volkswagen_golf_door_warnng_light_installation_19

Slide the pin back into place and clip the cover back into place.

volkswagen_golf_door_warnng_light_installation_20

Reinstall the connector into the base of the fuel lid switch and wrap the repair wires as shown to the harness using interior fabric adhesive tape.

volkswagen_golf_door_warnng_light_installation_21 volkswagen_golf_door_warnng_light_installation_22

Wrap the other end as well.

volkswagen_golf_door_warnng_light_installation_23

Slide the connector back into the housing.

volkswagen_golf_door_warnng_light_installation_24 volkswagen_golf_door_warnng_light_installation_25

Adding Door Puddle Lights to the Volkswagen Golf and Jetta

This guide covers the installation of the puddle lights to the Volkswagen Golf and Jetta front doors as fitted in some countries and specifications of Mark V’s and to some models of the EOS. Along with the Door Warning Lights these really light up the area around the side of the car.

The light operates every time the door is operated and stays on after you close the door (longer than the coming home time) but turn off when you arm/lock the car. When you unlock the car they turn on and stay on longer than the leaving home time.

volkswagen_golf_mirror_puddle_lights_finished_03

Adding puddle lights to the Volkswagen Golf or Jetta can be be achieved in two ways.

  • Purchase new mirrors with puddle lights fitted (estimated cost AUD$800/USD$400)
    • 1K1 857 507 BT 9B9 – Driver’s Mirror, power, heated, puddle lights (MY06 Golf/Jetta)
    • 1K1 857 508 BR 9B9 – Passenger’s Mirror, power, heated, puddle lights (MY06 Golf/Jetta)
  • Modify the existing mirrors to add a lense and suitable leds (estimated cost AUD$30/USD$25)
    • Trim Removal Tools
    • Selection of heat shrink tubing (3-5mm), soldering iron/blowtorch, solder
    • Vagcom/VCDS to code the door (this can be done before or after the install)

Volkswagen Golf & Jetta Door Controller Information Mark V has information on the door controllers. This guide was based on the install in my March 2008 build MY08 GTI.

First remove the door trim – Passengers Front Door Trim – Removal and Installation

The mirror cover – Removal and Installation of Mirror Covers from the Volkswagen Golf Mark V

And finally the mirror – Removal and Installation of Mirrors from the Volkswagen Golf Mark V

Extra cable to mirror

Adding extra cable to the mirror for the lights – this section can be skipped if you want to use the mirror heating cabling instead.

This is where the cable exits the mirror and enters inside the car.

volkswagen_golf_mirror_puddle_lights_wiring_01

This is the other end where the cable appears inside the mirror. Start by inserting the wire into the top and pushing inside.

volkswagen_golf_mirror_puddle_lights_wiring_02

The cable will be visible and you can fish it out with a suitable piece of wire.

volkswagen_golf_mirror_puddle_lights_wiring_03

Pull the wire through until you have almost enough to reach the controller. We need to wrap this cable next.

volkswagen_golf_mirror_puddle_lights_wiring_04

Using an exterior fabric adhesive tape – Fabric Adhesive Tape for wiring looms and harnesses – cover enough of the cable so that the part inside the mirror hinge and partway out each end is covered with two layers. This is especially important on the motorised mirrors that fold back.

volkswagen_golf_mirror_puddle_lights_wiring_05

Now pull the covered section through.

volkswagen_golf_mirror_puddle_lights_wiring_06

Leaving the uncovered section out like this.

volkswagen_golf_mirror_puddle_lights_wiring_07

Route the new cable as follows to follow the path of the existing cable.

volkswagen_golf_mirror_puddle_lights_wiring_08

And tape it to the existing loom.

volkswagen_golf_mirror_puddle_lights_wiring_09 volkswagen_golf_mirror_puddle_lights_wiring_10

This step identified Pin 10 as the positive power for the puddle light.

volkswagen_golf_mirror_puddle_lights_wiring_11

Insert the repair wire into the pin 10 position. Note. if you are using the mirror heater connection what you need to do is remove the pin from the mirror heater position and move it to pin 10.

volkswagen_golf_mirror_puddle_lights_wiring_12

Place a suitable piece of  heat shrink tubing (3.5mm to 4.5mm) on the repair wire, bare the ends of the repair wire and new wire to the mirror and twist them together before soldering.

volkswagen_golf_mirror_puddle_lights_wiring_13 volkswagen_golf_mirror_puddle_lights_wiring_14

Now pull the heat shrink over the connection and apply heat to shrink.

volkswagen_golf_mirror_puddle_lights_wiring_15 volkswagen_golf_mirror_puddle_lights_wiring_16

Using an interior fabric adhesive tape – Fabric Adhesive Tape for wiring looms and harnesses – wrap the new cable onto the existing mirror loom.

volkswagen_golf_mirror_puddle_lights_wiring_17

Replace the Door Mirror

Now reinstall the door mirror – Removal and Installation of Mirrors from the Volkswagen Golf Mark

Fit the puddle light and lense to the mirror

Depress the clips on the rear of the mirror at the points shown and pull the frame towards you as shown by the arrows and it will slide off.

volkswagen_golf_mirror_puddle_lights_fitting_01

Undo the two torx screws shown to release the mirror indicator and the lower housing from the mirror (torx T10)

volkswagen_golf_mirror_puddle_lights_fitting_02

Once the indicator and housing are hanging depress the clip around the middle of the indicator and the two will separate.

volkswagen_golf_mirror_puddle_lights_fitting_03 volkswagen_golf_mirror_puddle_lights_fitting_04

Work out where you want the lense to be installed taking into account clearance at the front of the mirror for the mirror assembly, the frame we removed earlier and the height of the LED module.

volkswagen_golf_mirror_puddle_lights_fitting_05

Drill from the inside of the housing using a hole saw  into some scrap timber (with paper towels on top if you don’t want to scratch the surface).

volkswagen_golf_mirror_puddle_lights_fitting_06 volkswagen_golf_mirror_puddle_lights_fitting_07

Next dremel around where the lense will go to increase the clearance for the LED module and to decrease the lip underneath the mirror housing.

volkswagen_golf_mirror_puddle_lights_fitting_08

Clean the surface with a suitable cleaner and apply some automotive silicone.

volkswagen_golf_mirror_puddle_lights_fitting_09

Push the glass into place and clean the excess off with mineral turpentine.

volkswagen_golf_mirror_puddle_lights_fitting_10 volkswagen_golf_mirror_puddle_lights_fitting_11

There will be a gap around the outside in which you fill with a 5 minute two part epoxy for strength. The silicone is mainly there for waterproofing plus the epoxy means after 30 minutes we can continue with the install. Remember to allow the silicone time to cure before you get it wet.

volkswagen_golf_mirror_puddle_lights_fitting_12 volkswagen_golf_mirror_puddle_lights_fitting_13

Fit the LED module into location and using 5 minute epoxy glue it into position, build the back up with double sided tape to provide mechanical strength.

volkswagen_golf_mirror_puddle_lights_fitting_14

The LED module glued into position.

volkswagen_golf_mirror_puddle_lights_fitting_15 volkswagen_golf_mirror_puddle_lights_fitting_16

Now reattach the indicator, route the wire (you will need to extend the stock wires, DON’T use the connector that came with it as they are useless and it will fail but instead solder the new ones and use heatshrink tubing) and check that the LED module is securely in place.

volkswagen_golf_mirror_puddle_lights_fitting_17 volkswagen_golf_mirror_puddle_lights_fitting_18

Removed the negative connection to the mirror and solder a wire to it and to the negative wire on the LED module before reattaching to the mirror. Use tape to connect the new wire to the mirror heater wire.

Note: If you are using the mirror heater wires for power detach the positive wire and solder a wire to it and the positive wire of the LED module but do not reattach the positive wire, instead pull it into the rear of the mirror and heatshrink it.

volkswagen_golf_mirror_puddle_lights_fitting_19

Both wires reattached to the mirror and the mirror surround frame slid back on.

volkswagen_golf_mirror_puddle_lights_fitting_20

Wrap the connectors up well to protect from water ingress.

volkswagen_golf_mirror_puddle_lights_fitting_21

Volkswagen Cornering Headlights, Dynamic Steered Headlights and Static Cornering Lights

The following information is for the Touareg but the principle is same on many Volkswagen cars with this feature.

volkswagen_cornering_headlights_1

Volkswagen’s cornering headlight system consists of dynamic and static cornering lights that are installed together in the headlight housing.

The cornering light functions are automatically activated when the dipped or high beam is switched on.

The cornering lights are also active if the headlights are switched on in daylight.

volkswagen_cornering_headlights_2

volkswagen_cornering_headlights_3

The Bi-Xenon units are swiveled independently when driving around bends.

The headlight on the inner side of the bend by max. 15° and the headlight on the outer side of the bend by max. 7.5°.

Swivelling only takes place at a vehicle speed above 10 km/h.

volkswagen_cornering_headlights_4 volkswagen_cornering_headlights_5

The design is very similar to that of a conventional Bi-Xenon unit.

However, the module is mounted in an additional swiveling frame (for the horizontal motion).

The sensor is for detecting the swivel angle.

volkswagen_cornering_headlights_6

The static cornering light is a light that is switched on in addition to the dimmed headlight. It illuminates the surface to the side of the vehicle.

The static cornering light is only switched on at a vehicle speed below 50 km/h in narrow bends.

volkswagen_cornering_headlights_7

volkswagen_cornering_headlights_8

Halogen light H7 for static cornering light.

The H7 light bulb can be replaced after removing the plastic bush

volkswagen_cornering_headlights_9

Networking between J745 (control unit for cornering light and headlight range control) and the power modules for headlights J667 and J668 via CAN light.

CAN light is a separate CAN databus only for networking the cornering light system.

Physically, the CAN light is identical to the CAN drive (voltage level, data rate and cable colors).

The power modules are installed in the headlights. The power modules process sensor signals (swivel angle of dynamic headlight and position of headlight range control) and control the respective servomotors.

The static cornering light is switched on and off by the corresponding power module.

All other lights in the headlight are switched by the on-board control unit.
