2002 3.0L Quattro A6 fog bulb light replacement
Just swapped mine out, my owners manual says "to difficult to get to bulbs, go to the dealer" . Well, I went in here and STFA, and found the H3 bulb callout and great instructions! But, for model/year of my C5 A6 however it's an H7, and it's just 3 #2 phillips screws on the front, unplug (like in instructions) and then pop the 3 clips on the side of the bulb case. Unplug the back from the H7 bulb, and then release spring clips holding H7 bulb in. Note how the H7 is in the bracket, remove it, swap in the new one, and reverse the procedure, total time to swap, 15 minutes, and that's with having to go hunt in my Audi parts bin for an H7 bulb. I even cleaned off my lens while I had it all open. Works great now!
