Overall, incredibly reliable, never a limp mode or other problem. The only "funky"item has been two (one maybe 2 years ago and another approx 3 months ago) really hard downshifts when approaching a red traffic light and the car was shifting from 3rd to 2nd it felt like the system just decided to drop the clutch, when I'm coasting with no throttle (I'm DCT).
Which "mass flow" sensor? The M3 doesn't have a MAF so you must be talking about the meter on the secondary air system? Strange..
The only 'real' issue I had on my car was the blower stopped working. Dealer fixed it, apparently a connector got hot, and they replaced it.
Other than that, 41,xxx miles and still drives like brand new. Best car I've ever owned. I will never sell it, just add more to the collection
I have extended warranty to 75k miles and maintenance for two more years, so hoping to get new brakes/rotors/ oil + tranny + diff fluid + brake fluid + microfilter + wiper inserts replaced before the two year end mark, and the $3300 paid for itself.
