Used Peugeot 508 Cylinder Head

The Peugeot 508 first generation ran from 2011 to 2018, with a facelift arriving in 2014, so a 2013 and a 2016 car sit either side of that facelift boundary. The engine code is the deciding factor above all else — if both cars share the same engine code (shown on your V5 or a VIN check), fitment is far more likely, but you should confirm with the breaker against your registration whether any ancillary or mounting changes were introduced at the 2014 facelift point. Never assume a match on year alone.

The second-generation Peugeot 508 launched in 2018 and brought an entirely new platform and revised engine family, so a cylinder head from the first generation (2011–2018) is very unlikely to be compatible with a second-generation car. Match the engine code from your V5 exactly, and confirm with the breaker against your registration before purchasing. Do not rely on fuel type or displacement alone, as the same capacity engine can carry a different code across generations.

For the Peugeot 508, trim levels such as Access, Active, Allure, and GT are cosmetic and equipment grades — they do not determine which cylinder head is fitted. What matters is the engine code, fuel type (petrol or diesel), and gearbox type, all of which can vary independently of trim. You may find cosmetic or interior differences when buying a part-out from a higher-spec car, but the cylinder head itself follows the engine, not the badge. Always quote your engine code to the breaker.

The engine code is the single most useful detail you can supply — find it on your V5 registration document or via a VIN check, and give it directly to the breaker. Also confirm your fuel type (petrol or diesel) and whether your car has a manual or automatic gearbox, as these details help the breaker identify the correct head quickly. Year of manufacture is useful for narrowing down the generation, but the engine code overrides everything else.

The body style — saloon or SW estate — does not affect the cylinder head, as this is a mechanical engine component that follows the engine code, not the bodywork. Provided the engine codes match, a head from an SW should be interchangeable with one from a saloon of the same engine. Confirm this with the breaker against your registration to be certain, particularly if the cars are from different model years.

A used cylinder head from the pre-facelift first-generation 508 (2011–2014) is a common and cost-effective option, provided the engine code matches your car exactly. Cylinder heads themselves are mechanical components and do not typically require ECU pairing, but confirm with the breaker whether any sensors or associated parts supplied with the head could affect your vehicle's electronics. As with any used part, have it inspected or pressure-tested before fitting where possible.
