Audi A4 xenon light problem

[Andyuk911]

A friend's wife 2005 A4 Avant has a strange problem with her xenon headlights.

They seem to randomly switch off independent of each other ... obviously this could be potentially very dangerous at night.

The local Audi dealer can't seem to find a fault.

Anybody else had this problem, but more importantly have any idea of a fix ?

Thanks

I'm sure there is a TPI about that, (would think your dealer would have checked for that) It even has a video of them flickering and going out for a second them coming back on.

Think its new burners/bulbs to fix. Need to read it again to be 100%.

I'd try the bulbs first failing that will be the ignitors.

My 05 S4 did this, needed a replacement ecu in the end.

Thanks for the notes.

TT, could you double check for me if you have a spare moment?

Thanks

I'm taking the head off a TTS tomorrow, It'll probably want an engine, have to take a look first.

I'll try and have a look through the TPI's for you at some point this week, but we're a bit busy.

OK, Thanks

I looked it up. and as above, the fix is new control units.
