As the title suggests this is about my A3's headlights. The previous owner fitted aftermarkets (not sure where from). I also have auto headlights/rain. The headlights work as expected. when switched to sidelight, only the sidelights(LED) come on. The same for dipped. When on auto mode and it gets a bit dark, the auto sidelights turn on - sidelight icon illuminates on dash. But outside the car both sides and dipped are on?? any suggestions?!
