Hydraulic pump at 200k.
Eats brake pads (every 40-50,000K), has to be the driving style.
The vacuum servo for the locks is quite problematic, had to use lots of Teflon tape to fix that.
Stereo system was a hard install, requires re-wiring.
Kind of low on power, must be the automatic transmission.
Absolutely amazing car, is great in the city and the highway. I can comfortably cruise at X kilometers above the speed limit and the car has that secure German car stability and solidity. Got a fully loaded German sedan for less than what I paid for my Mustang.
Great car for winter ski trips - stable and sticks to icy roads. HUGE trunk fits my and my girlfriend's camping equipment. I am sold on Audi and German cars period, would not buy anything else.
I owned a 85' 5000s and it was a jet.
Maybe a poorly maintained car?
