Second Hand Mercedes-Benz CLE Exhaust Manifold

The CLE (launched 2023) uses turbocharged four-cylinder and six-cylinder petrol and diesel engines, all of which have an exhaust manifold — so yes, this part genuinely exists on the car. However, on many modern turbocharged Mercedes engines the exhaust manifold is integrated directly into the cylinder head rather than being a separate bolt-on cast component, which means what you may actually need is a cylinder head assembly or a turbocharger inlet housing rather than a standalone manifold. Before searching for a used exhaust manifold, confirm with the breaker exactly how your specific engine code is configured, as the part you're looking for may be listed differently.

The CLE shares engine families with the W206 C-Class and W213 E-Class, so there is some mechanical commonality, but fitment depends entirely on matching the exact engine code — for example M254 petrol or OM654 diesel — not just the displacement or power output. Emissions generation also matters: a Euro 6d part and an earlier Euro 6b or Euro 6c part may differ in geometry around the turbo or catalyst connection points. Always give the breaker your registration and full engine code before assuming a cross-model part will fit.

No, trim level does not affect exhaust manifold fitment on the CLE — AMG Line, Sport, and EQ Boost trims all use the same engine variants and the manifold is determined by engine code and emissions standard, not by how the car is badged or optioned. You may notice cosmetic differences around the exhaust area (tips, covers) between trims, but the manifold itself is identical across trims sharing the same engine. Focus your search on engine code and fuel type rather than trim name.

The CLE is a first-generation model that began UK sales in 2023 and as of 2024–2025 is still in its early production run, meaning breaker stock is limited and most available units will be accident-damaged rather than high-mileage disposals. There are no confirmed facelift boundaries to navigate yet, so this generation boundary question does not currently apply — but if Mercedes follows its typical cycle a facelift could arrive around 2026–2027, and any parts sourced after that point should be checked carefully against your engine code. For now, confirm your engine code and Euro 6 sub-standard with the breaker, as even within a short production run Mercedes can make running production changes.

Yes, the diesel exhaust manifold (fitted to OM654-family engines) is a completely different component from the petrol manifold (M254-family) and the two are not interchangeable under any circumstances. The DPF and catalytic converter are part of the downstream exhaust system rather than the manifold itself, but the manifold's outlet geometry and mounting points are designed around the diesel aftertreatment package, so sourcing from a matching diesel donor car is essential. DPF and catalyst interchange specifics are strong confirm-with-breaker territory — give the breaker your full registration so they can verify the exact emissions sub-variant before supplying any part.
