I've noticed a significant increase in performance (driveability) now that my car has about 2200 miles. I wondered if anyone else has experienced the same. The surging in 1st gear has just about disappeared and the performance seems a lot crisper. My tailpipes were also black and sooty the first 2K miles and that seems to be improving also. Is it out of the question for BMW to have a rich "break-in" period programmed into the computer?

My dealer was emphatic that the car would act "better" after break-in and the car computer learning. They didn't put a timeline on it, though.

I have 1500 miles on my 335i coupe and it simply gets better and better. Maybe I'm still in the infactuation stage. I test drove a auto tranny, but bought a manual and it has so much outperformed what I expected. I love this car!!!!

Like all Bmws they get better with age , wait till after 50K, my 323is has 147K miles and runs like a tiger. Manual of course.

I've noticed my wifes 328xi Coupe is running better ....its been about 1,500 kms. Seems to accelerate better.

kinda makes sense since the internals of the engine are better lubricated, and, as mentioned above, the computer has adapted to the sensor inputs and whatnots.

All I know is it's increased the "fun" factor! I'm sure it's not doing anything for the gas mileage though...:D
