I made my official call to BMW NA to file my first official complaint about the hesitation at take off. I have STEPtronic.

I think they are having problems with this new 6 speed STEP tranny. As with all automakers, they keep it hush hush...

If you report it, the more reports will get the ball moving faster to fix it.

I was told they have a hard downshift problem too.

Can you be more specific/descriptive for non-experts like myself? Is this the same thing as when I step on the gas from a complete stop, and the car barely moves but the rpm gauge shoots up? I have an automatic btw.

Here is the answer to this "problem". It is just normal behavior of the Steptronic. Here is the text of my post to E90POST this morning with my guesses and a very important link to a post by "kahala12" who has posted facts which confirm the guesses.

Could it be that the "hesitation" is simply that in "normal" drive, the gear change algorithm is not very aggressive?

Would it help to think of "sport" as the natural home for the BMW driver, and the so-called "normal" position as the "laid back" program, while "manual" is the way to go for "serious" driving. Various posts indicate that the problem goes away in manual and I think that some members said it also goes away in "sport". RachelS said it was reduced in sport.

So, could it be that this "hesitation" thing is simply a matter of perception and expectation?

And maybe the "adaptive" nature of the transmission is part of it. Drive in a lazy, laid back way, and the algorithm gets lazy and laid back. Give it a caning and it responds with agressive gear shifts. Various posts indicate that the solution is to stomp on the gas.

Can't wait to get mine and try this out.

PS Just found this post which confirms my theory above

My close friend has put 400 miles on his 330 and his hesitation has definitely gone away so the car needs to learn your style.
