Hi, was wondering whether anyone knows the correct way to use the Steptronic on our E90's? Heard that there are basically 3 settings i.e. Auto, Sports (push it to the left & leave it there) and 'manual' (when you push it forward & back). Auto is pretty basic, but i realize that when i try to use the sports mode the drive doesn't feel smooth i.e. revs tend to go up & down like a see-saw. Chris1
