Advice for buyers
What should I look for in a used Audi A6 estate?
The Audi A6 Avant has a well-earned reputation for reliability. It's solidly screwed together using proven, good-quality parts and the engines will run and run without a problem if serviced properly. So that's the first thing to look for: a full service history.
However, pay particular attention to the suspension. This is the area that gives most trouble, according to data from independent warranty providers Warranty Direct.
You should have a good look over the rear suspension, especially if the car has been used regularly for heavy hauling duties.
Likewise, a car with a towbar should prompt you to check that the gears engage smoothly, without any slip from the clutch, and to look for any signs of a knackered engine, especially on four-cylinder cars.
Test all the electrics (the windows and warning lights particularly) and look for signs of heavy use in the loadbay and cabin. The A6 Avant is well built, but not indestructible.
