2006 Audi A3 2T...The previous owner installed aftermarket SpyderEyes headlights with LED strip...the required bulb for the headlights is H9. I'll describe the problem(s) in a moment.
I'm not looking for a definite answer about how to fix this problem myself. I am really ignorant with electronics, and 1) would like to understand the possible issues, 2) if someone could post a wiring diagram 3) and maybe some explanation on coding,etc.
So here is what I am experiencing:
1)Driver's side headlight out--I replaced with a new H9, it worked for about 6 hours then stopped working. Worked two days later at night for about an hour, then shut off and has never worked since.
2)The LED strip inside each headlight assy: Driver side strip works but half of the led's occasionally turn on or off. Passenger side led's turn on full when i start car, then shut off completely about 10 seconds later.
3)Foglights: I put brand new H7 bulbs in and they have never come on once.
I notice that the led's will react to things like pushing in the clutch, or shifting into reverse.......it seems random. I don't have a clue--but it seems like possibly a ballast problem in the driver's side headlight, and maybe a ground problem for the led's.....NO clue about the fogs.
Any insight is greatly appreciated.
I am taking my car to a performance shop this coming week, but I just want to know more about the headlight wiring and so on.
