Does that make sense??
does your engine seem to almost die but recover when coming to a stop? I had a similar problem in my previous M3 .. where sometimes when slowing down from a moderate speed to a standstill caused my engine to almost die and then recover .. happened occasionally. It was eventually diagnosed as a faulty idle valve and was repaired under warranty.
