I bought the car as a certified used car. The converters were replaced by Audi at 52000 miles and 69000 miles later I find I need to replace them again to the tune of 2500. It would appear the converters have a problem since I have maintained the car as directed by Audi and have always used premium fuel. I would be concerned about buying a used high mileage Audi. Other than this hit and front end suspension repairs this has been a good car to drive. Please send money. ;-)
Interior comfort and quality. Handling and feel. Just a great riding car.
Improve catalytic converter design and improver front suspension and alignment durability.
