Yep, same problem here. Dealer tells me the transmission is in learning mode while driving, but seems it's a very slow learner - and makes me look like one too! Seriously, this is the worst feature of the 4.8i, and I'm really beginning to hate it after 20,000k's in 10 months.

We drive for 200k's at constant speed using the cruise control. Then we hit the first traffic light, and it thinks my dear old grandma is driving. I press a bit harder, nothing, a bit harder, nothing. Then all hell breaks loose! X5 lurching around like a drunk teenager, kids terrified and the wife screaming at me! All I wanted was something in between...

Sport mode will solve the problem, but plays hell with your fuel consumption. And I really don't appreciate having to change modes just to make a smooth exit from traffic lights - isn't that why I bought an automatic in the first place? Never had this problem with any other car.

I feel your frustration, but can't offer a solution other than clear it's memory (ie. give it a good flogging and tell it who's boss). Might be just my imagination, but sure feels better afterwards!!
