I'm new to the site and was really hoping someone might be able to help me out on this issue, I've recently bought and fitted some genuine Audi Xenon headlight to my 2006 A3, they look great... only one problem when the headlights are turned on when the engines running they flash ON and OFF very fast, like a strobe light effect.
The only way I can get them to work is if I turn them on in the following sequence:
Even this sometimes fails to work first time.
- Ignition On
- Turn headlights On
- Wait for 10 secs
- Start the engine
Also to add to the problem if I turn my main beam on or flash my lights whilst the headlights are turned on they start flashing (again like a strobe light) and I can’t stop them without pulling over and repeating the sequence above, I found this out the hard way when I was coming back from work on the A19 at 11 at night and went to flash someone out. Scary!!
The headlights came out of my mates 2004 A3 working except from the ‘dipped headlight failure’ warning on the dash, which I also have, he didn’t experience any of the flashing problems I’m now having.
I’ve read bits and pieces about people removing relays and bridging across because the headlights don’t get the correct voltage on start up with the car having halogens in originally?? Don’t know if that’s true or could solve my problem? Also I’ve heard getting the car plugged into VagCom and the settings changed may solve this??
I’m at a bit of a loss now and if anyone has any ideas on how to solve this or could point me in the right direction, it would be greatly appreciated!
