When I used to take my Audi A6 in, unrelated things broke all the time, mostly due to idiots working on it. Forgetting to plug stuff back in properly etc....I have nothing bad to say about my BMW guys ..yet.
I also had the BMW softwre rev and a Dinan remap at the same time . My car growls a lot and runs great now...definitely not quiet..
