Anyone have a wiring diagram for the drivers door loom, pretty please?!

File is too big to upload here so I uploaded to my personal server. Will delete after 48hrs so download it please :)

Unfortunately the above doesn't really dive into individual connector pinouts. I've struggled to find a document that does this. I think that's a job for erWin

Much appreciated, thank you

If this is for the ambient lighting retrofit, please let me know your findings! I am also trying to do this.

Are you going with an aftermarket solution or are you retrofitting the OEM door panel trims?

Aftermarket, but having issues.

The main module has been wired to a switched live from the fusebox, comes on with ignition, dashboard led strip works as it should.

I intended wiring the door led modules to the inner door handle bulb, it's a switched live from when the doors are unlocked.

But, the door module won't respond to the trigger from the main module, I think they both go 'live' a few seconds apart, and they don't like that!

Spelling

By 'main module' are you referring to the aftermarket LED controller?

Whats the model name of the kit/module? Have you got a pinout/datasheet handy, i'll take a look and advise if I can.

Main module is the main led controller, the kit comes with the main and 4x sub controllers for the doors.

The main is piggybacked onto rear wiper fuse and works as it should with ignition on.

The doors, I'd planned to wire to door handle light, it's a switched + when you unlock the doors.

The issue I'm having is that the fusebox live, and the handle lamp live, don't energise simultaneously, and it upsets the led modules.

It's as if the main module cannot 'see' the sub modules.

The handle lamp is also modulated via PWM to dim the bulb, so as a power source/signal it's pretty useless.

I think your best bet is running a new, dedicated power feed into the doors for the sub modules, to ensure the whole system is powered at the same time.

The MQB platform is complex, and does some clever stuff. Accessory power feeds are computer controlled and usually don't correlate directly to ignition status.

AHH, understood 👍

But, isn't there a switched + in the doors , one I can tap into?

I'd rather not have to run a dedicated feed if I can avoid it, I'm not sure how I'd get through each door grommit!

I appreciate your help btw

Edited my previous post :)

I've had a look through the wiring diagrams and I can't see a switched ignition feed in the door loom.

I see, that's a shame...

How would I get a cable through the door grommit, I assume it's two electrical plugs connected together, is there room for a rogue cable?!

From memory, no.. The connector is sealed around a grommit.

You may be able to add extra pins into the connector, you can buy connector pinning kits quite cheaply online. Usually there's lots of spare pins on these for unfitted extras, one of those being ambient lighting which comes from pin 9 of the BCM. Sooooo, there should be space!
