Audi A6 Common Problems & Maintenance
The Audi A6 is a sophisticated executive car built on proven VAG mechanicals. A Cranbourne West VAG specialist covers the common A6 problems and how to keep one reliable.
A6 essentials
The C7 and C8 A6 use familiar VAG petrol and diesel engines with quattro and S tronic/tiptronic transmissions. Looked after with the right oils and on-time servicing, the A6 is a refined, dependable car.
Common A6 issues
Carbon build-up on direct-injection petrols, timing-chain attention on certain TFSI engines, water-pump and thermostat wear, and oil leaks are the regulars. Diesels need DPF/EGR care; the S tronic and quattro systems have fluid services that are often skipped.
Electrically, the air suspension on equipped models and the usual sensor niggles are worth checking.
Keeping an A6 reliable
Correct VAG-spec oil, sensible intervals, and the S tronic/AWD/air-suspension services done on time keep an A6 dependable. We use dealer-level VAG diagnostics and fixed written pricing.
