Our take on the Audi A6
A 2023 Audi A6 typically advertises at €39,950 and a 2018 one at €21,000, so it loses roughly 12% of its value a year at that age. Most for sale are diesels (74%), which suit longer, regular drives; for mostly short trips a petrol is the safer buy. At the NCT, the 2009–2020 cars do better than other cars the same year. The 2.0 diesel is the most common engine (79% of those with a known engine), and it usually lasts around 350k km.

Common Audi A6 problems
Known weak spots to check before you buy, with typical Irish garage costs if the problem is there.
EGR / DPF blocking (1.6/2.0 TDI) · €300–€900
Ask how it's driven: short trips clog the DPF. Any DPF/engine light, limp mode, or heavy smoke when revved is a warning.
Timing belt history · €350–€700
Ask when the timing belt and water pump were last done (usually every 160,000 km or 5–6 years). No proof = budget for it.
Automatic gearbox health · €300–€2,500
Make sure the gear changes are smooth when warm, check for a gearbox warning light and ask if the gearbox oil was ever changed.
Engines and how long they last
| Engine | Usually lasts | Motor tax / year | For sale |
|---|---|---|---|
| 2.0 Diesel | ~350k km | ~€270 | 481 |
| 2.0 Hybrid | ~300k km | ~€270 | 111 |
| 3.0 Diesel | ~320k km | ~€790 | 17 |
"Usually lasts" is the mileage these engines commonly reach before major work; service history matters more than the number.

Before you buy a used Audi A6
Run a history check on the reg (write-off, finance owing, mileage), ask when the timing belt was done and for receipts, and start it from cold yourself. The used car checklist takes you through a viewing step by step.
