I have a "Left Main Beam Headlight" warning message after turning my car on. I have a 2006 A3 2.OT with factory Bi-Xenons. The Xenon lights are working, yet I am still getting the warning message. Do the main headlights have 2 bulbs?? Also, the highbeam flasher is what is out? Can someone kindly provide me with some info since im afraid to take it into the stealership.
