my AT 06 325i makes a kind of rumble/creaking sound from the front end when I am trying to make the car creep just a couple inches from a stop and it vibrates throughout the car. it almost feels like the brakes are kind of stuttering or the clutch is engaging and disengaging rapidly making the whole car shake then it jumps forward farther than intended. it seems to be less violent when I downshift in steptronic into first and creep the car forward but it's still prevalent.
I can't really tell if it's the transmission or the brakes or maybe even a loose belt? or is it just normal?
:
anyone know what this is?
