I have 153k miles and no carbon cleaning yet! Run over 3000rpm for 30 min to burn off carbon, Audi has a patent for it. I would recommend 5k oil changes, and I'm in a hot climate running 10w-40 mobil 1. Original water pump, original timing chain.
That’s good to read; I do the same thing, and because I’m reaching 100k, I thought I would definitely need a carbon cleaning soon. I almost pulled the manifold off this summer and did the cleaning, because I didn’t want to be stuck doing it in the winter. This gives me more evidence that the 3k rpm for 30 mins is effective when it comes to keeping the valves clean
Just to add a little perspective, I've had to have carbon cleaning done twice on my vehicle; both about 65K apart or so.
She's my daily and I do mostly highway driving. Hard, close to redline pulls most days. I live in the 3K to 4K range. A lot of days I'm in that range for most of my commute. I don't even use 6th gear a lot of times...unless traffic is light and I'm moving along at 80-85+.
Point being, the Italian tuneup is no guarantee you won't get build up. I've used an analogy a few times on this site that I think is pretty accurate. Carbon in these cars is like earwax in people; some produce little to none, some produce a shitton and have to have it professionally cleaned.
Also, FWIW, have done 5K oil changes since new.
