Used Mercedes-Benz CLE Cylinder Head

The Mercedes-Benz CLE (C236 coupe, A236 cabriolet) launched in 2023 and is a brand-new generation with no direct predecessor sharing the same platform, so there is no earlier CLE generation to draw parts from. Fitment of the cylinder head depends almost entirely on matching the engine code exactly — check your V5 or run a VIN check to find yours before approaching a breaker. Never assume a head from a visually similar Mercedes will cross over without confirming the engine code matches.

Engine code is the single most important detail for a cylinder head — two engines with the same displacement and fuel type can have different bore dimensions, combustion chamber specs, or porting, making them incompatible. Your engine code is stamped on the engine block and also appears on your V5 logbook or via a VIN decoder; always supply it to the breaker rather than relying on badge size alone. Fuel type and gearbox type are useful supporting details but they do not replace the engine code.

Trim level — whether you have a standard CLE, a CLE 300, or a CLE 53 AMG — does not change fitment the way an engine code does; what matters is which engine is actually fitted, and AMG variants typically use a distinct engine code from the equivalent non-AMG model. So a CLE 200 and a CLE 300 with different engine codes will need different heads, but two cars both running the same engine code will take the same head regardless of whether one is a higher trim. Confirm the engine code with the breaker against your registration to be certain, as trim badges and actual engines fitted can occasionally differ.

It is possible that some engine families are shared across Mercedes model lines, but the CLE sits on a distinct platform and the cylinder head machining must match your specific engine code precisely. Do not assume a C-Class or E-Class head crosses over even if the badge displacement looks the same; supply your full engine code to the breaker and ask them to verify it matches the donor part before purchasing. A mismatched head can cause serious engine damage, so confirmation is essential.

Body style — coupe or cabriolet — has no bearing on cylinder head fitment; the head is determined by the engine fitted to the car, not the roof configuration. Both bodystyles are offered within the current CLE generation (from 2023), and engines are shared across them, so a head from a coupe donor with the same engine code is mechanically equivalent to one from a cabriolet. Always match on engine code and confirm with the breaker against your registration.

Modern Mercedes engines can involve ECU and immobiliser interactions that may need attention after fitting certain components, and this is something you should raise directly with the breaker and your fitting garage before purchasing. Whether a specific used head will require any reprogramming on your particular car is something to confirm with the breaker against your registration rather than assume either way. A competent independent Mercedes specialist or dealer will be able to advise on any coding work needed once the head is identified.
