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 often load a pushchair, dog or bulky bags: an estate layout could be useful. Try your own luggage rather than judging by the exterior size.
- 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.
Most 2018 A6 diesels are Euro‑6 TDI units paired to an automatic gearbox (7‑speed S tronic DCT on 2.0 TDI, or 8‑speed Tiptronic on V6s). Important diesel‑specific items to watch are DPF and EGR condition and AdBlue system operation — frequent short trips can cause clogging. Also note Audi parts and labour cost more than mainstream brands, and diesel demand has been softer since emissions concerns.
- DPF / EGR history — ask for evidence of successful regenerations and check for excessive soot or warning lights (short‑trip cars are prone to blockage).
- Automatic gearbox service history (S tronic/Tiptronic) — look for documented fluid/ mechatronic services and smooth, consistent shifts with no judder or hesitation.
- AdBlue system — check filler, piping and consumption rate; smell or leaks around the tank can indicate problems.
- Turbo behaviour and smoke at start/upshift — light blue/black smoke or turbo whine can indicate wear or oil leaks.
