Here's some links to the tranny reset procedure for push button start BMWs.

I had to adapt the procedure for my X3 with the turn key ignition. But it wasn't a big deal.

These BMWs have adaptive shift transmissions to more tailor the car to your driving habits. Remember these cars' throttle control are drive-by-wire which opens up the ability to record how much and how fast a person presses on the accelerator pedal. When you reset the tranny, it goes (back) into a generic shift pattern, from which it is learning how you press on the gas pedal to accelerate to a desired speed and what you do, once you get to that speed.

How we accelerate when we buy a brand new car, with 2 miles on the odometer is way different from how we accelerate when the same car is through the break in period, some 10 to 15K miles later...

Hope this helps
