  • Install in the reverse order of removal and ensure the trim is positioned in the door seal beading.

Rear seat noise (rattling, clicking and squeaking) in Volkswagen Golf

A common source of noise (rattling, clicking and squeaking) is the rear seat latches, when the seats move the lock mechanism moves around on the latch and makes a noise. You could try tapping them with a hammer from above to bend the latch slightly downwards but this doesn’t seem to fix the problem in most cases.

To test to see if it is the latches making the noise drive around with the seats lowered. If it is the latches the simplest fix is to wrap some electrical tape around the latch where the lock contacts it to stop the movement and remove the metal on metal noises. The fix should last for around 50 operations of the rear seats before you have to reapply the tape and only takes a few minutes and a roll of electrical tape (3M Temflex 1610 was used but any quality brand is ok, avoid cheap brands) in any colour except for body colour or black as you won’t be able to see if parts of the tape are stuck in the mechanism or if the tape requires replacing.

  1. Lower the rear seats
  2. Clean the latch with a suitable cleaner (99.7% Isopropyl alcohol or similar is suitable)
  3. Wrap 14cms of 3M Temflex 1610 electrical tape (or equivalent) which will give you six full wraps.
  4. Close the rear seat

(this is the tape after many uses, it should be replaced before it looks like this – I had started to peel it back prior to the photos)


(check the lock mechanism for any large stray pieces of tape that might cause problems with the operation)

Fitting GTI stainless steel seat inserts to the Volkswagen Golf GTI

volkswagen_golf_gti_seat_inserts_stainless_steel_010Volksagen Golf GTI stainless steel seat inserts are available on ebay for around USD$25 for a set of two (search for “gti insert” or similar).

Fitting is easy, twist them slightly to make them sit flush in the handle, clean out the insert position in the handle with a suitable cleaner and apply some clear silicone (sparingly) to the rear of the badge.

Adding switches to the blank switch covers in the centre console of the Volkswagen Golf and Jetta

Installing switches in the center console to utilise the blank spaces either requires purchasing the optional switch for that location from Volkswagen however these are a momentary switch, have different markings on them (W for example) and connectors for the switch are not readily available or fitting an aftermarket switch which looks out of place. This guide uses an off the shelf switch and no-one would know the switch is there unless they press the button. Whilst this guide is performed on a Golf Mark V the same blanks are used in the Golf Mark VI so the same switch can be used and the same principles can be applied to any other car with a similar setup.

As an alternative there is a company called CarStyle4You that sells buttons with different engraving that match the OEM buttons and they also sell suitable oem switches. See the end of this guide for their details and a few sample photos.

The switch used here is a latching switch but momentary is also available. The switch illumination can be used but as the ends are removed you will get white light spilling out the sides so upgrading the internal light to a coloured LED gives a nice glow around the switch.

The switch used to be available from RadioShack in the US but they don’t seem to carry them anymore.

To allow the blank to fit and move freely the two sides of the switch around the cover of the switch must be removed, not that the base width must not be altered as it’s a perfect width for the centre console.

Remove the plastic in the switch as shown and roughen the surface on the bottom of the switch in preparation for gluing.

Perform a test fitting of the switch and the switch blank to make sure it all fits together. Glue the cover from the switch and the switch blank together, roughen the surface of the switch cover and use a two part epoxy (5 min araldite or similar).

Clip the switch and the switch blank together and test the operation.

The finished switches ready for fitting to the centre console. When soldering the wire on keep the connections tight as the retaining nut has to fit over the soldered connections.

Fit the switches and align them on the front (there is limited adjustment) and screw the retaining nut down tight. Once aligned use some two part epoxy (araldite or similar) to lock it tight and prevent the retaining nut from working it’s way loose. The wires have been taped up using Fabric Adhesive Tape for wiring looms and harnesses and connectors fitted around 300mm down to allow easy removal of the central console.

CarStyle4You sell suitable engraved blanks and switches that match the OEM ones and can be illuminated. I may organise a few of these switches and post a separate guide/review as the quality looks top notch and well worth the money.

CAN bus gateway removing, installing and upgrading – Volkswagen Golf

The role of the Gateway (also known as the Data bus diagnostic interface J533) is the exchange of data between the CAN data bus systems (‘powertrain CAN data bus’, ‘convenience CAN data bus’ and ‘infotainment CAN data bus’) and the conversion of diagnostic data from CAN data bus systems to K-cable and vice versa so the data can be used by vehicle diagnosis, testing and information systems like the dealer VAS tools and Vagcom/VCDS.

For various reasons including power drain issues with third generation head units or the addition of new unsupported modules the CAN bus gateway must be upgraded to a newer revision. This guide covers the replacement of the CAN bus gateway in a 2005 MY06 Volkswagen Golf GTI. The upgrade replaces the 1K0 907 530 E (1K0907530E) with a 1K0 907 530 AA (1K0907530AA).

This process works the same for most Volkswagen models.

1K0 907 530 E (1K0907530E)
Revision: 11

1K0 907 530 AA (1K0907530AA)
Revision: H16

Record current installation list and long coding

Take screen shots or make a note of your installation list in controller 19 – Can Gateway using Vagcom/VCDS. This step is critical unless you want to figure out what you had installed prior to the upgrade. Don’t be tempted to copy down the long code unless you are installing the exact same revision of gateway as different revisions have extra features.


Whilst not essential it is worth taking a screen shot of the different screens in the long coding.

Removing and Installing the Gateway

Remove the key from the ignition or disconnect the car’s battery (the battery disconnect is optional but better safe than sorry)

Remove the footwell cover on the drivers side where the gateway is located – Volkswagen Golf footwell cover drivers side – Removal and  Installation.

The gateway can be in two locations on the Golf. One is above the accelerator pedal and the other is above the clutch pedal (if fitted). The clutch pedal location was used for the first year or so of production.

  • Release the connector and pull the connector off the data bus diagnostic interface.
  • Press three securing pins together and push out of holes to release or the holder is hinged and release that.


  • Install in the reverse order of removal.

Reconnect the battery

Coding the new gateway

Using the screen shots and notes from earlier you can now recode the gateway. Below are screenshots showing the differences between the two gateways (old gateway on the left and new gateway on the right
