My 2012 A6 3.0tdi quattro is starting to have some faults and i cant find out what it is.
in heavy traffic (rush) the car is in 2 gear , and idle down under 1000rpm, and you try to throttle you can feel it shaking hard for like 300rpms.
and in reverse you get a metallic vibration sound.... somebody expirenced the same ? best regard JR from norway.
