..or more importantly why I am having this particular problem.
I had an accident recently and part of the repair was the replacement of a complete headlight including the xenon bulb & ballast.
Now occasionally when turning on the headlights the new headlight does not start, I then turn off the headlights and back on then it comes on as normal. I have tried and failed to make this reocurr, I took it back to the repair garage, as all there work is guarenteed, they had the car a full 2 days and did not once get a failed start from the headlight, so returned it to me explaining they cannot fix it if it isnt broken, it has happened twice since.
The older unreplaced headlight up to this point is unaffected.
I have scrounged the old headlight back off the repair garage and tonight as a little test replaced the new xenon bulb with the old one, which failed to start every time first time after unplugging and replugging the power cable to the back of it, so I swapped back to the new bulb which doesnt have the same symptoms as the old bulb, hmmmmmmm.
I am not a xenon light expert, my intuition is now pointing at the ballast on the new light.
Oh and worth mentioning I never had this problem before the accient either.
Car is a facelift 2001 Audi S3.
