it must be because you need to put the repair wire in a different pin. you're right that for the 8P3 the wiring is different, but if you know the pins you can swap them over no bother. your best bet is to ask someone for the pin diagrams off ELSA of the plugs to the headlight switch. once you know that it should be pretty straight forward. compare the two and instead of putting it in pin 12 like the diagram, put it in the new pin - that is of course unless the new CECM doesn't allow it at all.

Argh, you're building encouragement again Sub, stop it  :grin:

TBH it's very unlikely the Control module would allow it as it seems pretty restricted compared with the 8P2 BCM that I've interacted with, but that's guessing.
I've got the enthusiasm, the time and the budget to try it - just not the skill or experience in terms of electronics  :confused:

Is the pin diagram going to shed any light at all?

i think the CECM will be the problem more than the pin... sadly the post-facelift CECMs i have little knowledge of

Hmm. Who's best to speak to?

I've got VCDS and I'm reasonably good with it, happy to try different bits out in there if of course VCDS coding will allow the BCM to support the rewiring(?)

The CHome and LHome values can even be enabled and set in my DIS alongside VCDS too, so the coding side shouldn't be as big a challenge perhaps?

if you're a member of Audi Sport there's a Scottish chap called Phil who facelifted a prefacelift S3. this makes him pretty much an expert at 8P electronics (he did all the work himself). i know on VAGOC his user is Phil, but i think it might be P5 SND on Audi-Sport. ask him and tell him i sent you!
