stumble/jerk when cold and in manual mode
Anyone else getting a stumble or jerk when coming to a stop or starting while engine is cold? I'm talking about when the car is cold and has sat overnight, while driving in manual mode (in first gear), at speeds of 0-3 mph or 3-0 mph. When you let off the brake to move, car jumps a little. Or when right before coming to a stop, it jerks forward then stops. Only happens when cold for a few minutes. Once engine warms, it's gone. And only in manual mode.

never used manual mode when the engine was cold.
never revved more than 2.8k rpm until engine & trans get warm.
btw M3's trans never lets you to rev more than 4k rpm when the engine is still cold.
even IS's brakes dont work well in cold.
I feel more grip from the brake after it warmed up. esp when it gets hot, it works a lot better than any other disk brakes. other cars fades away but IS doesn't

And this happens when you are in manual mode? I don't experience it when in auto mode. And yours happens at the same low speeds when coming to a stop or starting? Like 0-3 mph or 3-0 mph? Any mention to your dealer or fix?
