this is what i did.
in vcds controller 46 - Comfort System/coding
my original code was: 0000251 so i added 0131072(Highline LED) which gave me:0131323 and clicked do it, everything seems fine accept reverse and fog.

the problem is:
with the car in reverse, the fog light turns on.
and with the rear fog switched on the reverse light turns on?

can anyone please tell me what i did wrong, or better still (and i know this is cheeky) maybe you could tell me what code to put in?)

thank you in advance

 

I don't have an answer for you, but I am curious why you recoded your taillights.
