In the first D program (D1) the car will start in 2nd gear (I think the manual says this too). When the engine is cold D1 (or any 2nd gear start) will cause it to surge/lunge a bit. Once it warms up this does not happen unless you are really light on the gas pedal. So I have two solutions:

Don't use D1 mode. It is seriously wimpy for an M5.

If your engine is cold let it warm up before using D1. Once warm give it a bit more foot ... after all you're starting in 2nd gear it needs so go-go juice.
