paddle to the floor , when you feel your paddle with a "click" , it'll vroom

that seems to be the simpliest you can do

I think it prob is manual. my 330i used to do the same thing. Its to do with the "fly by wire" technology on the accelarator peddle (no cable to the engine) and how the clutch is fed into drive when pulling away, if its not done in a way that the ECU "dislikes" it results in a feeling of hesitance, mine even felt like it was going to stall at times....
