Cheap Mercedes-Benz X-Class Cylinder Head

The X-Class ran as a single generation from 2017 to 2020 with no major facelift, so the production window is relatively short and consistent — but fitment of a cylinder head is determined by engine code first, not model year. Provide your engine code (found on your V5C or via a VIN check) and ask the breaker to match it exactly, as small mid-run specification changes can affect ancillary fittings. Never assume year-for-year compatibility without the breaker confirming against your registration.

Yes — the engine code is the single most important detail for this part, overriding the year, badge, or anything else. The X-Class shared engine architecture with Nissan Navara (NP300 platform), and the cylinder head is machined and ported to suit a specific engine variant, so even engines that sound similar on paper can differ internally. Pull your engine code from the V5C or a VIN check and give it to the breaker before anything else.

No — trim level (Progressive, Powerful, or Power) does not affect cylinder head fitment; these trims reflect interior specification, equipment, and styling rather than mechanical differences. What matters is the engine code, fuel type (diesel in every UK X-Class), and whether any specification changes were made to your specific engine during the production run. Confirm the engine code with the breaker and ignore the trim badge when sourcing this part.

The X-Class generation ran 2017–2020 without a distinct facelift, so on the surface the years look interchangeable, but cylinder head compatibility still comes down to matching engine codes rather than production dates. There were no major publicised engine revisions across this window, however minor ancillary or mounting changes within that period are something you should confirm with the breaker against your registration. Match the engine code first and let the breaker verify the rest.

In the UK market, every Mercedes X-Class was sold with a diesel engine, so you are unlikely to encounter a petrol-engined donor car from a UK breaker. However, if a donor vehicle has been imported, the engine code will immediately reveal the difference, so always ask the breaker to confirm the code from the donor car matches yours. Mixing diesel and petrol cylinder heads is not possible, but sticking to UK-sourced stock largely removes that risk.

No — the 3.0-litre V6 diesel and the 2.3-litre four-cylinder diesel are entirely different engine families with different cylinder head designs, and the parts are not interchangeable. The V6 unit also has two cylinder heads (one per bank), so you need to confirm with the breaker which bank (NS or OS) you require as well as the correct engine code. Always quote your full engine code when requesting a quote to avoid any confusion.
