Propellerhead suggested to re-flash the tranny.
I also posted the
same thing here and some other posts.
Report back after.
P.S. :After re-flashing you should follow the BMW 2-1 tip-in procedure. Basically, take it for a short drive, and EVERY TIME YOU COME TO A STOP, make sure you count to 5. ABSOLUTELY NO ROLLING STOPS. After driving and having 6-7 full stops, turn the vehicle off, wait a few and she's golden.
