it's a facelift '03 plate S3 with Xenons, and i've been having an intermittent issue with the offside (drivers) dipped main beam.
For example, if i start the car, drive to fuel up, engine off. Start up again to drive away, switch lights on, the beam is out and the "bulb out" symbol flashes up on the screen. Sometimes switching them off and on again rectifies it, other times it's as if the bulb IS out -which it's not.
It's currently down the auto-elecs shop and he recons it's the ballast igniter, and that Audi have quoted him 500 spondoolies for the full light unit rather than just the failed component. Doesn't seem right to me. Has anyone heard of this problem before??
BTW...Great site with bags of info that's come in handy for me in my 10 months of S3 ownership. Keep up the good work!
