I just purchased an 08 335i. Just over 1600 miles and for the past few weeks rough starting - hang up at 100 rpm then jump to start idle. This morning the same happened with a considerable shake from the engine and stalled. Driving out the car stalled but then started fine and drove perfectly.
options - bad fuel ???
orThe dreaded 335 fuel pump failure--thought these were fixed on the 08 models...
