BMW issued a recall on the 3 SERIES model

On certain M3 vehicles equipped with the multistage downshifting of the double clutch gearbox, during some cases involving rapid vehicle deceleration, the transmission software may perform a multistage downshift. In this situation the clutch is open for a approximately 200msec. When this occurs, positive gear engagement is interrupted. In conjunction with the engine's over run fuel cut-off at low speed, there is a possibility for the engine to stall. Loss of propulsion, in conjunction with traffic and road conditions, and the driver's reactions, could increase the risk of a crash. Correction: Dealers will re-program the Engine Electronic Control Module.
