Yes but I got them from tire rack this summer mounted and balanced on new wheels. The culprit seems to be the steel stick on weights. They are less malleable then lead weights which are now illegal. And because they can't be bent to match the contour of the wheel they have a poorer contact area and are more likely to fall off. I'm just surprised that the weights are the culprit, upon further inspection there seems to be on square weight that is missing in the rear.

Mine only does that in "sport" mode. In "D", it brakes smooth as butter, but in "sport" braking is a little, jittery, I guess would be the word.

Agreed. My old E90 330i did it too. Figured it was a BMW thing. No?

check your brake rotors

guys i honestly dont think my brakes would cause my whole car and engine to shake and sound like a diesel while parked in my drive way ..this happens mostly after using the trip tronic ..specifically the "M" part of it. i experienced this the other day, will be taking it in to the shop tomorrow and see what it might be..

yes you can, stick key in, get electrics on, press gas pedal fully 2-3 times and hold for 25 seconds is what it was i believe..this is what i did before but dont remember exactly the seconds or how many times to press down
