I didn't on the RS4 but having cooked a set on the road and the stuff on forums about issues on the 3,4,5 and 6 I don't really have confidence that I'd not cook them again.
Mine get noisy and vibrate a little when very warm which I know is a character of these but doesn't instill confidence.
Just don't seem to hear of hear issues on Beemers do you.
Probably because BMW designed them better........
Oh Crap now i've gone and done it, paid a compliment to BMW.
