Our take on the Audi A8
A 2023 Audi A8 typically advertises at €66,900 and a 2017 one at €25,950, so it loses roughly 15% of its value a year at that age, faster than most cars. At the NCT, the 2011–2019 cars do better than other cars the same year. The 3.0 diesel is the most common engine (74% of those with a known engine), and it usually lasts around 320k km.

Common Audi A8 problems
Known weak spots to check before you buy, with typical Irish garage costs if the problem is there.
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 |
|---|---|---|---|
| 3.0 Diesel | ~320k km | ~€790 | 14 |
| 3.0 Hybrid | ~300k km | ~€270 | 5 |
"Usually lasts" is the mileage these engines commonly reach before major work; service history matters more than the number.
