Good evening, today on the passenger side the xenon light just failed. Then I expanded the bulb/burner at home (whatever you call it now). I bought an Audi A6 4b 2.8l Quattro a few weeks ago. Through the Tüv he came without faults. The previous owner told me that the xenon was retrofitted. I am now looking for a few hours after xenon burner with the H1 socket, but find nothing right. Is my first car with Xenon and I am not so knowledgeable yet. I thank you already in advance and wish the rest a nice Wednesday evening.
