Second Hand Peugeot 108 Cylinder Head

The Peugeot 108 ran as a single generation from 2014 to 2022, receiving a facelift in 2018, so both years sit within the same overall family — but the facelift boundary means ancillary details can vary. The safest approach is to match on engine code first: check your V5 or run a VIN check to get the exact code, then confirm with the breaker that the donor head shares that code. Never rely on year alone when crossing a facelift boundary.

Engine code matters above everything else for a cylinder head — two 108s of the same year and fuel type can carry different engines depending on market or specification, and the head is machined to suit that specific block. Pull the engine code from your V5 logbook or a VIN check and give it to the breaker; this is the single detail that will confirm or rule out compatibility faster than anything else. Fuel type and year are useful supporting information, but they are not a substitute for the code.

Yes — petrol and diesel cylinder heads are completely different components with different combustion chamber geometry, valve sizing, and in diesel applications the provision for injector and glow-plug threaded bores. The Peugeot 108 was sold in the UK with petrol engines only, so if you are sourcing from a UK breaker this is unlikely to cause confusion, but always confirm fuel type with the breaker alongside your engine code to be certain.

Trim level does not affect cylinder head fitment on the Peugeot 108 — Active, Allure, and Collection trims share the same engine options and the head is determined by the engine code, not the badge on the tailgate. You may find cosmetic differences between donor and recipient cars when the breaker strips the head, such as different ancillary brackets or covers, but the head itself is what matters. Confirm the engine code matches and ignore the trim designation entirely.

The Peugeot 108, Toyota Aygo, and Citroën C1 of this generation were built on a shared platform and use the same engines, so a cylinder head from a matching engine code in either of those models is potentially compatible with your 108. Match the engine code precisely — do not assume all years and variants are identical across the three brands, as specification can differ at certain points in production. Confirm the engine code and any ancillary fitment details with the breaker before purchasing.

Gearbox type does not directly affect cylinder head compatibility — the head bolts to the top of the engine block and is chosen by engine code, not transmission type. That said, some engine and gearbox combinations were paired with specific ECU calibrations, and if the donor vehicle's engine management setup differs from yours there may be coding considerations; confirm any ECU or immobiliser implications with the breaker against your registration rather than assuming a straight swap. Focus on matching engine codes and let the breaker advise on any ancillary differences.
