probably a simple question for most of you but bear with me.....i have an 01 a6 qith the xenon headlights and one headlight is blue and the other is yellowish.....which from my understanding suggests that the yellowish one is older....i want to change them both so they are both the same, the manual says to bring it to a dealer for this but i was just woundering if it was possible for me to do it, and how. thanks in advance.

 

I would first swap the bulb side to side to make sure its the bulb, and not the igniter.
