Common SEAT Arona 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 |
|---|---|---|---|
| 1.0 Petrol | ~280k km | ~€180 | 282 |
| 1.6 Diesel | ~350k km | ~€190 | 15 |
"Usually lasts" is the mileage these engines commonly reach before major work; service history matters more than the number.
