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 Automatic Hatch Opening

(This mod has turned out to be unreliable over time as the springs compress – a new mod using replacement struts and bumpers supercedes this one –  Volkswagen Golf Automatic Hatch Opening Updated)

Automatic opening of your Volkswagen Golf rear hatch is possible with a few easy changes. Not all cars will work so try the first part requiring VCDS/Vagcom before proceeding.

In VCDs/Vagcom change Byte 2 Bit 3 in the Central Convience Controller 46.

Once this is done when you press the hatch open button on the remote the hatch will pop out about 10mm. If this works then proceed to adding the springs.

The springs on the left of the first photo are the correct ones to use with a size of 31.77mm long, 17.4mm wide and a spring wire thickness of 2.2mm, these were available from Mitre 10 and Bunnings along with other hardware stores in Australia but they are hard to find now in some areas. The spring on the right of the first photo cut into two is not suitable, it didn’t quite have the power required to keep popping the hatch.

The second photo is of a new spring stocked at Bunnings from the Century Spring Corp, the C-712 is very close to the specifications of the first spring at 31.75mm long, 17.475mm wide and a spring wire thickness of 2.337mm. The spring retails for AUD$4.75.

Warning, when you pop the strut off in the next step make sure you have an assistant or a broom or similar to hold the hatch up as it will drop and it’s very heavy.

Lever the clip back with a flat head screwdriver, don’t pop the clip completely off as it will be very hard to get back on. It takes a little force to pop the socket off.

This is the end of the strut with the end of the strut removed. To remove this use two pairs of vise grips and either plastic or a towel to protect the surface of the strut shaft and the end of the strut. Carefully remove the end piece and put to the side.

New spring before installation, the old spring actually fitted perfectly into the end of the strut, the new one requires some crimping of the end as pictured to reduce the outside diameter and it’s now a snug fit into the end of the strut.

The cap on the end of the shaft has been removed, using some pliers with a towel this doesn’t take a lot of strenght to remove.

The spring is now slid down and sits nicely in the end of the strut.

The spring should hold in the end of the strut by itself.

Cover back over the end of the strut

The cover install over the end of the spring and strut. Put silicon over the outside of the strut but make sure not to get it on the strut shaft as there may be some issues that arrise from silicon in that area. The cap will be a firm fit.

Follow the above instructions in reverse to refit. Then repear for the other side of the car.

All going well you should now have auto hatch opening.
