They checked Chrysler for any mention of it and found nothing. He also said they can't access the Mercedes database even though they are the same company. I'm getting fed up with the hassle. I'll take my car to a new dealer closer to work in a few weeks when I have time and try to start the process all over again. Maybe I'll get someone who's willing to work with me.
Yeah... i didn't get satisfaction until my third dealership... although the 1st 2 i didn't have the tech papers...
As far as the MB database... the third dealer didn't have access either although did utilize it ... assisting them to pinpoint... they had made copies of it so that the service manager and the XFtech had hardcopies.
In my case... the DRONING occurred because of the module's malfunction... sending misleading info that caused the torque converter to stutter and the drive shaft and rear differential to cough... my droning stemmed from rear-passenger side-wheel...
How long have you been experiencing this? Where do you feel the vibrations? How often and when does it occur (as mine started off once every week or so then progressed to EVERYTIME the engine hit the 1,300-1,800 rpm mark and the vibration was loud enough to be heard from outside the XF).
When at the dealer, were they able to replicate the vibration?
Lastly... don't run of patience...
