Not getting much help on the B7 forum, so trying my luck here.
Okay, got the European headlight switch from ECS Tuning and installed it (easiest mod yet!!)
The package included the little yellow control wire that you can pin into the switch and CECM for activating rear fogs.
My question is, if I complete the CECM wiring and enable the rear fog bit inside of the VAG-COM; are my rear lights fog ready, or do I need new tail lights + different tail light wiring?
Anyone with any pointers would be much appreciated!
