Our take on the Audi A5
A 2023 Audi A5 typically advertises at €39,900 and a 2018 one at €23,000, so it loses roughly 10% of its value a year at that age. Most for sale are diesels (68%), which suit longer, regular drives; for mostly short trips a petrol is the safer buy. At the NCT, the 2008–2014 cars do better than other cars the same year. The 2.0 diesel is the most common engine (75% of those with a known engine), and it usually lasts around 350k km.

Common Audi A5 problems
Known weak spots to check before you buy, with typical Irish garage costs if the problem is there.
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.
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.
Engines and how long they last
| Engine | Usually lasts | Motor tax / year | For sale |
|---|---|---|---|
| 2.0 Diesel | ~350k km | ~€200 | 240 |
| 2.0 Hybrid | ~300k km | ~€200 | 63 |
| 2.0 Petrol | ~220k km | ~€420 | 19 |
2.0 Petrol: usual problem: heavy oil use and timing chain.
"Usually lasts" is the mileage these engines commonly reach before major work; service history matters more than the number.
