I would flash the updated DCT and DME software.

I used ZB# 8606072 (135iS) for the DCT, and PPK flash for the DME.

The original software caused the car to roll back and forth ever so slightly when in P, and also had common RPM surge when coming to a full stop with the A/C on.

Immediately after buying the car, I flashed the above versions of the DCT + DME software and re-calibrated the setpoints for the DCT in ISTA. I have absolutely no issues at all for a month now. It drives fantastically.
