Doesn't happen all the time but since I've taken over my new A6 (C6) Avant, there are times when one of the headlights (bixenon)doesn't turn on and I get a light out warning.

If I turn the lights on and off with the switch, it usually comes back on.

Anyone else have this issue???

It may be the bulb itself. Before you buy one, swap the left and right Xenon bulbs to see if the issue moves with the bulb. If so, then you know the bulb is the issue. I have seen this occur already, just on a different model.

Yeah, sounds like the bulb(s) are starting to go bad. I had the same promblem with my B7 A4. When it happened to me I took it to Audi and the charged me $130 to tell me that the bulbs needed to be changed. It was $730 for 2 new bulbs and labor from Audi. Crazy, ... I called up ECS tuning orded a set and took it to my friends mechanic shop ... problem solved!!! Do be cheap with the bulbs though, each one had its own balast.(hope I spelled right)and change both at the same time with german brand. I have have adaptive headlights which work fine just like they used to. The lights are brighter too because I went with 4800K instead of the stock 4000 or 4300K. Let us know how you make out.

I have exactly the same problem.

Sometimes if I turn the light on then off and back on within a short time.

For example if I turn my car on and off within a short time my right headlight sometimes will not turn on and I get the "lights out" warning.

My Audi mechanic has said to me that it may be the bulb or it may be the igniter.

It is most likely the bulb. I believe the Osram brand Xenon bulb was the ones I seen do this. Once they are on, they work. It's only once the bulb is turned off and back on again, it may not light up.

Thanks all.

I'll swap the bulbs and see how that goes.

It's the igniter. Have it changed.

My mechanic said the igniter failing is a common issue.
