Peugeot 508 buying guide (Ireland, 2026)
What a used Peugeot 508 costs in Ireland, how it does at the NCT, what goes wrong and what it costs to fix. Based on 140 for sale right now.
Our take on the Peugeot 508
A 2023 Peugeot 508 typically advertises at €23,950 and a 2017 one at €8,500, so it loses roughly 16% of its value a year at that age, faster than most cars. At the NCT, the 2012–2020 cars fail more often than other cars the same year, so a fresh NCT is worth paying a little more for. The 1.5 diesel is the most common engine (36% of those with a known engine), and it usually lasts around 320k km.

Common Peugeot 508 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 |
|---|---|---|---|
| 1.5 Diesel | ~320k km | ~€200 | 24 |
| 2.0 Diesel | ~380k km | ~€270 | 17 |
| 1.6 Diesel | ~280k km | ~€200 | 14 |
| 1.6 Hybrid | ~300k km | ~€190 | 11 |
1.6 Diesel: usual problem: injector seals, turbo and DPF fluid.
"Usually lasts" is the mileage these engines commonly reach before major work; service history matters more than the number.
