Transmission, what else is new. I had to replace it 500 km ago.
I'm having problems with starting it up. Cold-start I guess.
Power steering makes a grinding noise, but works fine.
And a leaky hydraulic oil reservoir.
Good amount of passing power. Extremely comfortable.
I agree with your findings in regards to cold weather starts.
I own one in South Africa. Great car, important to use correct hydraulic fluid for the Steering to avoid leaking problems. Incorrect fluid attacks the seals in the power steering rack. causing leaks.
All Audi cars are like that! Always use recommended fluids or the car gods will not be happy!
I have a 1990 with 208,000 miles and it still runs great. The original transmission lasted 135,000 miles, so far so good on the second. The starting problem is probably caused by leaking fuel injectors, have had mine replaced 3 times, always corrects the problem. American gas is very hard on the fuel system, especially injectors. The exhaust manifold has a small leak that should be fixed, but repair is a little expensive. Sunroof motor gave up a couple of years ago. Otherwise, everything works, very comfortable, very safe car.
