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.
