Spanner can help turn your car details into an advert.
Could suit you if…
- Your usual group fits within 5 seats, including the driver. Check passenger space and any child-seat fit in person.
- You regularly make longer journeys: diesel may fit that pattern better than a routine of mostly short trips. Compare actual running costs.
- You would prefer less gear changing in traffic: the recorded automatic transmission may suit. Try how this exact gearbox behaves on a test drive.
Think twice if…
- You need to carry more than 5 people together: the advert records 5 seats, including the driver.
- Most journeys are short school runs or local trips: check whether this diesel has a particulate filter and what longer runs its handbook requires.
- You need servicing to fit a tight budget: Spanner estimates higher maintenance costs for this type. Get quotes for the exact engine and gearbox before committing.
This is general guidance about this type of car and your needs — not an inspection or approval of this individual car.
Diesel A6s from 2018–2021 are popular for motorway work and often have diesel-specific systems: DPF and AdBlue are fitted and need proper long runs to avoid clogging or frequent regen cycles. The automatic gearbox must be serviced at recommended intervals (fluid/filter changes); some A6s also use mild-hybrid electronics, so ask if the car has the 12V MHEV system and verify electrical behaviour.
- DPF condition and evidence of regular long runs — short-trip use can lead to blocked DPFs.
- AdBlue system and injector for faults or unusually high consumption.
- Automatic gearbox service history (fluid/filter change) — ask when this was last performed.
- Turbocharger for shaft play and oil leaks around turbo and oil cooler seals.
- If fitted, check air suspension operation and level sensors (expensive to repair on higher-spec A6s).
Spanner’s our AI mechanic — always have a proper look at the car in person before buying.
