Hi, ive been searching this for a while now and have found mixed tutorials and methods but am not sure which will work for my car. I have the a4 b7 2005 s line model with standard headlights no auto lights and no auto dimming mirror. this fit is on an a3, will it work on mine? This is exactly what i want. cominghomelights - Audi Retrofit Ive also found others but im not the best at electronics and not sure about lowline / highline models? http://bigskyeuro.com/images/gallery/mikewire/pdf/CHLH_retrofit.pdf Any ideas if this would be possible? Or anyone know someone that can do this for me? Thanks!!!!!
