tintinmt Posted April 15, 2019 Share Posted April 15, 2019 Hi, my wife's S4 (B7) Cabrio has developed a headlamp fault. They seem to go on and off occasionally. Usually just one side goes off and on again. Sometimes the whole lot seem to go out. I have trawled the various past posts but still have questions. I have recovered from realising that the bumper really needs to come off and can do this. What should my plan be? Do I need to get bulbs?, igniters? ballasts? Where should I source the parts? If I just replace the bulbs and that fails to cure, do the igniters and ballasts require the bumper off again? Would I be better off just replacing the whole lot in one go? Cheers.
