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 109 for sale right now.

Our take on the Peugeot 508

A 2023 Peugeot 508 typically advertises at €23,950 and a 2016 one at €7,950, so it loses roughly 15% of its value a year at that age, faster than most cars. Most for sale are diesels (79%), which suit longer, regular drives; for mostly short trips a petrol is the safer buy. 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 (38% 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.

Engines and how long they last

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.
