At the NCT, the 2011–2021 cars do better than other cars the same year. The 1.4 petrol is the most common engine (46% of those with a known engine), and it usually lasts around 300k km.

Common Audi A3 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.
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.
Engines and how long they last
| Engine | Usually lasts | Motor tax / year | For sale |
|---|---|---|---|
| 1.4 Petrol | ~300k km | ~€280 | 394 |
| 1.0 Petrol | ~280k km | ~€190 | 171 |
| 2.0 Diesel | ~350k km | ~€270 | 121 |
| 1.6 Diesel | ~350k km | ~€200 | 95 |
| 1.5 Petrol | ~300k km | ~€400 | 70 |
"Usually lasts" is the mileage these engines commonly reach before major work; service history matters more than the number.
