T6.1 fog-light retrofit

[wazza.w]

Success with my Fog light installation. (back home on Leave, I work away)
Using VCDS I was able to make an adaption to recognize the added switch position for the front Fog lights.
Could not find how to do this with OBD11 using a Pro license.
The cornering lights were functioning after doing the adaptations with OBD11, not the fogs, received a headlight fault if I left the switch on in the front foglight position.
Attached VCDS photos for information.
So I now have an OBD11 Pro and a VCDS Hex Net to play with.

Hello, new to the forum, I have t6.1 startline and have added a new bumper with front fogs, I'm ok with the wiring( I think) but struggling with vcds. Do I need to do all the wiring into bcm and new switch before adaptation with vcds and if so so can anyone talk me through it as I'm not familiar at all. Some told me you can't add new fogs into bcm using vcds but have to use an online coding service, so not really sure what to do now.
Any help will be greatly appreciated

Welcome,
If you go back and read my posts you will see I was in the same situation, but got there with out too much trouble. Need to replace the light switch with one with the additional position, you use “adaptations” in either VCDS or OBD11 or similar to add additional position to the BCM to recognise the switch.
Wiring to lights from BCM pins 40 and 3 (from memory) mine work as fog lights from the switch, they work as cornering lights at any time and also illuminate when reverse is selected

Hello again, I'm after so more info if possible you mention left goes to pin 40 right goes to pin 3 and switch pin 9 goes to 47, but which plug on bcm? I have 3 A,B,C

left goes to pin 40 right goes to pin 3

46 pin connector T46b (brown) - so I guess it's the "B"

switch pin 9 goes to 47

73 pin connector T73a - so most likely the "A"

Many thanks, not the easiest plugs to get at but I'll give it a go in in the week

what is the best way to get at the plugs so you can add the cables, i can see the from the bottom but struggling to get in close, would the top be easier with the clocks out

update, have got to the conhnector now and the T73A akready has a cable in so ok with that, the other 2 pins T46B I can get at but the pre wired crimps i have a too small, I dont suppose anyone has a part number for these that fit?

Just checking, have you changed the actual rotary light switch itself?

Yes have a new switch in with the double pull for front and rear fogs, it already had the wiring from t73a, I'm missing something just don't know whst
