Vibrations in the new 3-series
I recently bought a new 320d (F30) that was delivered in June 2012.
It has a sports suspension but no adaptive chassis.
Immediately I felt vibrations in the steering weel between 70-120 kph.
It feels somewhat like driving an old car with unbalanced wheels. I contacted my local BMW dealer and they have now gone through the car, including steer-box software, wheels, brakes etc. but the problem remains. They now "wait for orders from Germany". I understand that other owners have experienced similar problems.
Does anyone have more info about these vibrations and what they might originate from?
