Hello! Welcome to justanswer!
I'm not sure if its related to the service unless someone at the dealership pushed the vehicle too hard during a test drive. Usually vibration like you describe comes from the drive shaft u-joints or the drive shaft center bearing. I would have both items inspected. They are usually responsible for a vibration while on the gas.
Just to clarify...
Your opinion would be that the onset of the vibration was a coincidence and not related to the dealer service?
I have seen posts on some of the forums suggesting an inner CV joint in the front drive axles... but... the coincidental timing is annoying.
Dealer says "they all do that" referring to the vibration.
John Sterling at BMW of Sarasota is the service manager who I recently spoke with.
We got a final repair from the dealership...
No defects noted in the driveshaft or driveshaft bearings/couplers.
They finally put the driveline computer into brand-new vehicle "learn" mode again... and the vibration went away.
But I had to INSIST that they do it at all.
It was at my suggestion that they try the reset. They whined about doing it.
Thanks for everything!
Oh No... please don't misunderstand!
I wanted to let you know the final resolution. I had asked them at first about the computer and they rejected it out of hand (too much effort?).
I was and am extremely happy with your help (your comment about not accepting the "they all do that" answer was pivotal in getting the dealership to do the right thing). I'm really glad to have found this service, and appreciate your help!!!
Thank you very much. I appreciate the feedback and again I'm glad your vehicle is working properly. Please come back anytime you need assistance.
