Seems that the surging in mine is worse the colder it is outside and only first thing in the morning. I have 48,000 miles and am taking it to the dealer this Saturday. (09 550i)
The dealer was able to duplicate the problem and are opening a case with BMW, we shall see. ***** Update They did the software update and after I test drove, it didnt fix anything. So on to mechtronics work I assume.
