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.
The 2018 A6 diesel/automatic frequently appears with Audi’s S tronic (dual‑clutch) or torque‑converter automatics and needs gearbox fluid/service at recommended intervals — missing that history causes costly repairs. Diesel A6s are also fitted with DPF/EGR and (on many Euro6 cars) AdBlue; these systems work best when the car is used regularly on longer runs. If the car is quattro all‑wheel drive, check rear diff/transfer box service records as those add extra maintenance points.
- DPF and EGR condition — ask for evidence of regular motorway runs or a recent forced regen; repeated short trips can clog the DPF.
- Automatic gearbox operation and service history — no hesitation, clunks or delayed upshifts; verify any fluid/servicing was done per Audi schedule.
- Turbocharger play and smoke on cold start or under load — tell‑tale of oil leaks or turbo wear on older diesels.
- AdBlue system (if fitted) — check dosing, sensor lights and that the filler cap is present and functional.
- Suspension bushes and rear subframe area for wear or knocks plus brake disc/pad condition — 8 years old is when bushes and mounts commonly need attention.
