Just saw your post about the affordability of OEM filters. Cost does not bother me, but my local Audi dealer is 1) a pain to get to and 2) a pain. I bought the A6Q there, but swore I would not buy anything else there. What's a good source for the OEM filters? I can't even find Mahle filters locally for the car. TIA, Samuel Samuel W.
