i have an 02 a6 3.0 with a headlight out. i bought a new xenon bulb, which didn't fix the problem, so i'm afraid the igniter is bad. if the igniter is bad, is it something that is easily replaced? has anyone had a problem like this? thanks

 

Yes I called me close friends at my local audi dealership. They replaced it in 5 mins and the bill was 76.14 for both headlight and one igniter.
