I was driving back home two nights ago and the front left xenon light had a flicker, then I realised it went off. I had no warning from the panel, but I pulled over and the light was definitely off. I had a bit of Italian swearing going on :rant: and then got back in the car.. I switched the lights off, then on again and the light was back to life like nothing happened! Any ideas/similar experiences?

I believe that most if not all HIDs can have issues with their ballasts when subjected to a series of on & off demands. The Ballasts have some sort of timed safety circuit that will prevent permanent damage. Were the Autolight On-Off swithched on and was the menu set to high sensitivity?

This could explain it, or as Nev (a 159 Guru), questioned; a dodgey connector? Remove all connectors and check for corrosion, lubricate (vasaline's good for this(seriously!))

Let us know how you get on!

I noticed something similar happen to a friend's car (an Audi) as we parted company in a car park in Watford a couple of years ago. I stopped him and pointed it out, and he drove away with the light out. About 30 minutes later the car cremated itself big time on the hard shoulder of the M25 - although there wasn't enough of the engine compartment left to determine if the fire and the headlamp fault were linked in any way ...

The autolight was off, I tend to keep my lights on even during the day (it's a habit from when I was in Italy). Will check for loose connectors, although it seems quite a hard spot to get into.

gulp! :eek:

Well, last night I went out and the lights seemed just fine. It was a one off thing, just very odd. I was actually wondering what's the lifespan of a Xenon light, do they fade/burn?

I fitted a set of GTA zenons to my brothers 156 and experienced the same issue.
The standard lights worked fine but with the Zenons the left one kept on flickering and then if switched on and of will work again.
I found that there were a power drop on the wire (not 12v but 10v) added a relay and all is fine.
So in short yes I think you have a bad connection.

Had this happen on the after market HID's I fitted to my Soarer. Pulled off the connector and refitted it and no problem.
