1) Push the key in the ignition without foot on break.

3) Press and hold the accelerator all the way to the floor for 20-30 seconds
4) Turn off power
I recently purchased a 2011 135i and noticed the same issue. I was so used to my F30 shifting smoothly, especially when coming to a complete stop that I was starting to wonder that something was wrong with 135i's transmission. Yesterday I was stuck in bumper-to-bumper traffic on 101 and once i clear the traffic jam and came to a complete stop at a next traffic light, car did not quite jerk or lurch, but something was going on in AT and it was more noticeable.

I did just the above, + waited 2 min after reset to start the engine and it sure helped. I read on bimmerpost forums that it resets AT actuator, or something like that, but not a throttle reset.

Shifting is much smoother now and AT does not jerk when coming to a stop, or at least it's not that noticable.
