Hi, I have an 2001 Audi 4 quattro 2.8T, and its original headlights are xenon, I decided to get new headlights, the bulbs in the new ones are not xenon so at first I bought just the xenon bulbs, didn't work so I did research and I needed the kit, bought the kit and got it to work, now the problem is that everytime I turn my car on the warning sign on the cluster tells me that i dont have headlights but only if I switch the lights on and sometimes it beeps continously and other times doesnt beep for like minutes. This is my first car so If I could use some help would be great, thank you.
