Hi guys
Story goes, 2007 A6, rear o/s lamp looses all power to stop/tail/reverse/indicator etc, shut off engine & restart and all works for a few minutes, been told its a rear lamp control unit. Has anone came accross this fault? Know where the control unit is? been told there are 3 similar control units together somewhere !!
