2011 Audi A8 4.2 TDI
 

I have an issue with my Car there is a Vibration coming through the floor at low idle ( 700 - 800 rpm) which disappears when you are accelerating or travelling at normal speeds from 30 -120 km's / hr.

AUDI service Agents don't know what it is, we already had the latest software update and the plug and play technology is not telling them anything. they say engine and gearbox mounts are OK .

Has anyone had similar issues and if so how did you fix it ????

66,000 k;ms ( 41,000 miles).

This vibration is driving me absolutely crazy. It is no fun to drive.
