So a while ago I retro fitted xenon headlights into my 2007 audi a4 b7 8E.
The old bcm module would no accept any changes (8E0 907 279M) so I swopped it out for (8E0 907 279N) as advised on here to do and now everything works .....sort of!
I have just realised my rear fog lights will not work with this control module I can test them via vcds and they work fine but not on the switch?
Swopped back to the old control module and everything works as it should (rear fog lights work to)
I have fitted another bcm with the same code (8E0 907 279N) and its doing the exact same thing no rear fog lights.

Does anyone know what is going on has anyone had this issue

I also have an issue with vin learning on the new unit when typing in 26992 in adaptations its displaying disabled 10.0? anyone know why and how to get around this

Previous thread for reference:

Would you be so kind as to post an Auto-Scan of the car in its current state?

i posted this before however due to issues with my laptop it had to be sent away for repair,
anyway...

i have retro fitted xenon headlights into my audi 2007 a4 b7 i fitted a new BCM Module (8E0907279N) everything works but i cannot get my rear fog light to work instead my headlights come on ?
when fitting the orginal BCM Module 8E0907279M and standard halogen headlights my rear fogs will work like they should ,however i cannot code this moduel hence why i replaced it with (N).

As you can see theres a fault for the light switch i have replaced it twice but the fault remains this only appears when i fit the 8E0907279N Module not the (M)
Do i need to replace my light switch with a different model ?
if so does any one know what the part number would be or is this something i can sort on vcds as im at a dead end!

Current light switch installed is - 5K7 8E0941531 C 5PR

Thank You.

Users cannot delete threads. Starting over fresh is rarely desirable, as it loses the contextual information of what has come before.

Anyone?
or could this be something i have done wrong or missed when coding the new BCM module?

As far as i was aware all i needed to do was install new BCM Module (8E0907279N) then on VCDS go to 09-central Elec, 10-adaptations 081-component protection -46992 and test then save then go to 07- coding and change the fourth digit from zero to two to activate xenon headlights with drl's coding will be 10021 instead of 10001 am i missing anything else possibly something needs changing in the long coding?

Have you checked that the long coding and ALL the adaptation channels in the new BCM are identical to those in the old BCM?

Adaptation channels yes and there identical ,as for the long coding no as I'm still learning this and not sure how to get into it ,I'm assuming that il need to login (11) first to access the long coding?

Waxing pedantic: These modules ( 8E0-907-279) don't use long coding; they use old-school short coding.

so could this possibly be a light switch issue then as it's throwing a fault when the module is fitted but not when the old one is ,maybe the BCM module will work correctly with a particular model of light switch?
I'm just throwing ideas now as I'm completely lost on what to do ,I'm now into my third module (two N's & L) and there all doing the same thing!
i know its just a rear fog light so nothing major but I'm OCD and i know it will just annoy me.

if there's a way to get my old module (M) to accept the coding changes that would be great as everything works as it should with that one .

That's what I'm wondering: Is it possible that these two different modules are expecting two different light switches? One would have to take a fairly deep dive into a parts catalog to know for sure.

so been a few days now and I'm still not any better off i have tried a good handful of light switches all different part numbers and I'm still having the same issue as for the parts catalogue iv had a look around but cant find any useful information.
so my next option is my original BCM unit and getting it to accept the coding change (8E0907279M) as this unit actually works , at the moment when ever i change the coding the page refreshes but the changes don't apply is there a way around this?
if not then I'm going to give up as this is becoming an absolute headache for something that should be a straight forward job.
