The Best Used Audi Models

3 min read

Audi builds some of the best-looking, best-driving vehicles in the segment — and some of the most demanding to own. The gen-3 EA888 2.0T (2017+) resolved the timing-chain-tensioner problems of the earlier generations. Records and an independent VAG specialist are essential.

Ownership

Maintenance Expectations

Audi ownership is meaningfully more expensive than mainstream — budget for gasket work and turbo service.

Independent VAG specialists cut dealer costs substantially. Find one before you buy.

5,000-mile oil intervals are the safe practice — 10,000-mile intervals are too long for EA888 turbo engines.
