I have a brand new complete set of oem hids, 10-12 pin harness adapters and Vag-Com. I placed the hids on the engine and connected the harnesses disabled Dlr's, enabled bixenon w/shutter installed. the part # for the cecm is 3c0-937-049 q which I believe is the highline because I previously installed the oem fogs to the cecm and they function properly. The hids don't light up, no turn sigs or parking lights and then throws a lamp code. The car is an 06.5 tdi model, is there other modules needed? Can someone that has made this install explain please?
