Did mine a week ago and have not had one rough shift since.
For those that this did not work for, maybe this doesn't fix the problem you have with the car.
Just a thought.

Well I keep forgetting to post this but I forget what post I read it in so started a new one so nobody would miss this. If you have an auto and experience any "rough" shifts. For example for me it is when I would downshift from 3-->2 and ESPECIALLY from 2--> 1, it would feel like my car was a rocking chair.
Well then someone posted a tip and links to other threads on this in different forums I believe and was confirmed by a BMW tech who chimed in on the thread-and it WORKED well for me.
You put your key in/hit start ONCE so the electronics of the car come on but it is not started.
Then hold down the gas, past the downshift point to the floor for 25-30 seconds straight.
If you listen, at about 25s exactly you will hear some "noise" and that is the tranny "resetting" itself to factor specs
Like I am sure you know these cars are smart and the auto tranny is no exception. It adapts and learns your driving style-but the catch is, which is why I noticed an improvment. Apparently it "learns" for about 1000 miles and then kind of "locks" those settings in so-to-speak. So however you drove the car off the lot or whover drove it off the lot-it was really those first 1k that determined how the autobox shifted itself.
So anyway after I did that my downshifts were like 10 times smoother and overall shifting was much crisper and smooth.
Definetly try it out if you have an auto. It will just re-adapt to your current driving style-which is great since I totally drove different when I first got the car.

Does this work on a 335i?

it does not work on my 2004 either, must be a software issue. I reset mine with INPA loaded laptop. But more than anything changing my autobox oil helped a million to smoothness.

The only shifting problem I have with my 08 528i is that sometimes at a stoplight, when hitting the gas to go it clunks very hard and lurches forward. Will this fix that. No, I did not read all 22 pages of this thread.
Put the key in, hit the START button enough to turn the electriciy on, hold the gas pedal all the way down for about 30 seconds and I should hear some weird noises. Is that correct?
