I too thought this car was noisy coming from a 335i and was wondering what was "normal" vs. of concern. This thread cleared it up and put my worries to rest. It is a noisy, mechanical beast, especially at start up. Someone once told me, think of a it like a Swiss Watch, and it's finely tuned mechanisms.
