Second Hand Mercedes-Benz CLE EGR Valve

Only the diesel variants of the CLE (those fitted with the OM654 family four-cylinder diesel engine) have an EGR valve; petrol-engined CLEs do not use EGR in the same way and will not have a conventional EGR valve to replace. If you have a petrol CLE and are chasing an emissions or running fault, the part you need is likely something else entirely — confirm your engine code with a breaker before ordering anything.

The CLE-Class launched in 2023 as a single-generation coupe and cabriolet (W236 platform), and the diesel versions use the OM654 engine family — confirm your exact suffix code (e.g. OM654.920 or similar) from your V5C or by giving the breaker your full registration, as small differences in the code can mean a different EGR configuration. All of these are Euro 6d-compliant engines, so you need a part sourced from a like-for-like Euro 6d donor car rather than anything from an older emissions era. Never assume a visually similar valve from an earlier Mercedes diesel will drop straight in.

Because the CLE shares the OM654 engine family with certain generations of the C-Class (W206) and E-Class (W213/W214), there is a reasonable chance of compatibility if the engine suffix codes match exactly and both cars are from the same Euro 6d era — but you must confirm this against your registration with the breaker rather than assume it, as calibration and pipe routing differences can exist between body styles. A breaker with the donor car's registration to hand can cross-reference the part number properly. Do not fit a part from an older C-Class or E-Class on a different emissions standard.

No — trim level has no bearing on EGR valve fitment whatsoever. What matters is your engine code and emissions standard, both of which are the same across all trim grades that share the same diesel engine. You may find cosmetic differences around the engine bay between builds, but the EGR valve itself will be the same part; confirm the engine code and you are looking in the right place.

The CLE did not exist before 2023, so any part from an earlier car crosses into different model-year and potentially different emissions-standard territory — even if the OM654 engine family was used in older cars, detail differences in Euro 6 sub-variants (6c, 6d-temp, 6d) mean the valve specification may differ. Name the boundary plainly: 2023 onwards is the entire CLE production run so far, and anything older is a different model entirely. Confirm compatibility part-number to part-number with the breaker using both registrations before purchasing.

Give the breaker your full registration so they can confirm the OM654 engine suffix and verify the donor car is also a Euro 6d vehicle — mismatched emissions eras are the most common reason a visually identical EGR valve causes problems after fitting. Ask for the donor car's mileage and check the valve for carbon build-up or damaged actuator pins before fitting, as these are common wear points. A reputable breaker should be able to cross-reference OEM part numbers between donor and recipient to give you confidence before you commit.
