What owners reported
Source: NHTSA complaint databaseOwners of the 8 model years this bulletin names have filed 399 complaints with NHTSA since 2015. 14 of them name Power Train — the same broad component group this bulletin is filed under. NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.
The all-wheel-drive clutch in the vehicle had to be replaced. The symptoms were heavy vibrations or thumping when starting to drive forward from a stop with the wheels turned in either direction. A dealership - New Country Audi of Greenwich - did the repair at a cost of $4,308.85 (including tax).

A few minutes into the drive the transmission oil is too hot warning light came on and the car went into a 'limp' mode, car could only be driven less than 10mph. If this occurred while making a turn or in the highway it could have been disastrous or even fatal.
