Finally got round to fitting the jacking point mods today. Works a treat, thanks Kev!  :smiley:

Glad to help.

The mk7 and I will soon be parting ways. Need something with rear doors and a bigger boot. I can't find anything that will properly fill the mk7's shoes. Every option I look at is a compromise in some way. The GTI was such a complete car.

Passat TDI 240bhp 4 Motion: Has all the tech and I'm familiar with VW (VCDS, parts, mods etc). It's not the sportiest looking car on the road. There's no 240bhp passats in Ireland to test drive. Also the thought of a 4 cylinder diesel does not give me the warm and fuzzies.

BMW 330d/430d:Gran Coupe: My initial choice. Great engine for a diesel. Low tech compared to others and mediocre interior let it down. I also have no tech knowledge on BMW's so would be at dealers' mercy.

New A4: Bland bland bland! The old B8 was better looking/proportioned. The standard spec is poor so I would be looking at retrofitting ACC and other options that are now standard on the GTI.

Audi S3 saloon: My preferred choice but pricey to run. Petrol is 10c per litre more expensive than diesel here. I'd probably loose 5-7mpg on the GTI. Also standard spec is terrible. Auto dimming mirror and dual zone climate control is extra FFS!

So here's a bit more detail on the door warning light mod. Again, I didn't intend on doing a how-to so I don't have pics for every step. Also note some pictures are of the drivers side and others are of the passanger side in case you notice that the 32 pin plug has extra wires in some pics. The driver's side has more wires in it.

This mod was easier to do on mk5 and mk6 as there were empty positions in the door controller to accept the wiring for the door warning lights. If your car has illuminated door sills, this is fed from the door warning light position on the door controller. This makes sense as the sills only illuminated when the door is open, and only the side with the open door illuminates. This makes the wiring more difficult as you have to somehow tap into this feed but on the other hand the door controller already has door warning lights activated (to power the sills), so no vcds coding is necessary.

The power for the sills and lights comes from pin 16 on the blue 32 pin plug in the door controller. I could not find an empty ground pin in the plug on the door controller so i decided to tap into the ground already at pin 5 in the 32 pin plug.

If you dont mind damaging the car's wiring then you can just get tap connectors and take your power and ground from the wires going to the pins mentioned above. I avoid doing this if possible. My solution is to build a loom that plugs in between the car's loom and the 32 pin plug. I then spilt the power and ground in my loom. The advantage of this is that the home-made loom can be removed and the wiring returned to factory spec without any signs of modification.

Parts needed:
Light:..............1K0 947 411 A......1 per door
Plug:...............1J0 971 972.........1 per door
Repair wire:.....000 979 019 E......1 per door
Repair wire:.....000 979 009 E......1 per door
Repair wire:.....000 979 012 E......1 per door
Door card clip:..7L6 868 243.........3 per door
0.5mm2 Thin Wall wire:...............3m per door
VW loom tape
Shrink tubing

* The A3 wiring diagram shows 0.35mm2 wire but I'm fairly sure the A3 uses leds for the door warning lights. As we are using a regular bulb, 0.5mm2 is safer.

Here is a quick sketch of the wiring loom you need to make. The 019 repair wires go in the plug. The 009's go at the far right end of the loom and the 012's are used on the little spurs off. Note that the drivers (right side) needs a slightly longer loom. This is because the 32 pin plug is closer to the door hinge on the right door.

Use a ring spanner to turn the plastic clip at the bottom of the door card 90 degrees:

Pop off the cover to the grab handle:

Remove the one bolt behind the cover an dthe other below the grab handle:

The next bit requires brute strength and care. Pop all of the clips holding the door card on. You are pretty much guaranteed to break some so do get spares.

Remove the door card and unplug the wires. Note 2 light fittings have the same plug so you could plug them back in the wrong way round. They are a black 2 pin plug. Mark which ones goes to each light. I didnt do this and it took trial and error to figure out which went where! I didnt remove the cable from the door handle to door lock as I was worried I would break it so I just let the door card lean up against the door while I worked.

This is the right side door controller with blue 32 pin plug:

Remove the plug, cut the cable tie holding the cables to it and release the white plastic piece from the blue cover.

The 2 wires we are interested in are the brown at pin 5 and the purple at pin 16:

Remove these pins from the plug and lie them back along the loom towards the rear of the door and plug in the ends of the new loom in their place:

Next join the purple and brown wires from the car loom to the spurs in the new loom. These pins will plug securely and easily hold themselves together. Put some heat shrink tubing around them to hold them together and insulate.

Now tape the loom to the existing car loom, put the 32 pin plug back together and fit a new cable tie.

Here is a picture showing the left side with the plug back in but the wiring not yet taped up and secured. You can see the 2 new grey wires coming from the 32 pin plug. These are the terminals to the far right in my diagram. You can also see the purple and brown wires that used to be plugged into the 32 pin plug. The shrink tubing on the brown wire covers where it plugs into the spur on the new loom. The purple wire wire is also joined in the same way but it's obscured by the thick bundle of cables.

The pic below is of the right side with the plug back in but the brown and purple wires not yet joined to the new loom. If you are wondering where the other spur is, you can just see it to the left of the thick brown and red cables going into the door controller.

Tape up the loom and run it beside the existing loom through the 2 hooks. Then turn it down toward the bottom of the door. In the pic below, you can see that I taped it to the door to secure it.

Now plug in your light to test it works before you refit the door card. You may need to close the door lock with a screwdriver and open it again to get the door controller to power up the light. If the sill lights up but the door warning light does not, you more than likely have the polarity wrong. Swap the pins around on the plug going into the light and try again.

If it works remove the light again and refit the door card with the wire poking out through the hole where the reflector is located. And Voila! Door warning lights are done!

I know, massive bump. Can anyone tell me how the wire lengths relate for a 5dr mk7? I'd prefer making the looms before taking the car apart to install them.

Wire lengths are great for a 5dr Mk7 - done this mod to my 5dr without any issues at all.  :wink:

Awesome, I was just worried they'd be too long to properly route. Thanks again, looks like I have something planned for the weekend ;).
