to reset it just drive is more aggressively. that worked with the 330i.

i used to slap it into the manual gear change mode (that puts it into sports mode) the shift would hold til redline and also downshift when braking and holds the gear so you can acclerate out of turns.

now i don't need to do it since I've started to drive a little more aggressively in the "auto" mode. the upshift are done at near or at redline depending on the throttle position, etc.
