IN THAT SITUATION, AT LOW VEHICLE SPEEDS, IT IS POSSIBLE FOR THE ENGINE TO STALL INCREASING THE RISK OF A CRASH.
BMW is recalling 2008–2009 M3 passenger vehicles with the optional double clutch transmission. When rapid vehicle deceleration occurs, the transmission software may perform a multistage downshift, which can cause the engine to stall, increasing the risk of a crash. Dealers will reprogram the engine and transmission ECU with updated software free of charge.
