I'm throwing codes 2CF6 and 2CF7 (throttle valve potentiometer with possibility to mass air).
I've heard others having the same problems after getting their car serviced. I'm still trying to fix the problem. I'll be checking the O2 sensors this weekend, hopefully that fixes the problem.
Your issue is not hte same as the OP issue, which doesn't throw any codes. Take your car to the dealer or a BMW tech that can appropriately diagnose your problem.
For the record, my issue is still occurring, with no codes every being thrown. I've also replaced a substnatial part of the PCV system and vac lines which were failing a smoke test, and will be doing another section of it (the last I think), in the coming weeks. At this point, I've tried so many things, I'm not sure what the heck is causing it.
