Cheap Mercedes-Benz S-Class Oil Pump

These are from different generations — the W221 ran from 2005 to 2013, while the W222 began in 2013, so a 2010 donor and a 2014 recipient are on entirely different platforms with different engines. Even if both cars share the same engine code on paper, crossing that W221-to-W222 generation boundary means ancillary and mounting details may differ, so you must confirm compatibility with the breaker against your registration. Engine code is the key detail to have ready.

Engine code matters above everything else for an oil pump — the S-Class has been sold with a wide range of petrol and diesel engines across its generations, and each engine family (for example M272, M273, OM642, M278) uses its own oil pump design. Year alone will not tell the breaker enough, because multiple engine variants were on sale in any given year. Find your engine code on your V5C or via a VIN check before requesting quotes.

Yes, fuel type is directly relevant because petrol and diesel engines are entirely different units with their own dedicated oil pumps — a pump from an OM642 diesel will not fit an M272 petrol engine regardless of the car's age or badge. Always specify your fuel type alongside the engine code when contacting a breaker. Matching the engine code precisely is the safest way to ensure you are quoted the correct part.

The W221 S-Class ran from 2005 to 2013 with a facelift arriving in 2009, and within that generation oil pumps are fundamentally tied to the engine code rather than the facelift year. If the donor and recipient cars share the same engine code, fitment is likely, but whether ancillary or mounting details changed at the 2009 facelift point is something you should confirm with the breaker against your registration. Provide your engine code to the breaker so they can check against the specific donor vehicle.

Trim level and badge names like S350, S500, or S63 AMG reflect different engine variants rather than cosmetic differences, so in this case they do matter — but only because each badge typically denotes a specific engine code, not because trim itself affects fitment. An S350 diesel running the OM642 needs an OM642 oil pump; an S500 on the M273 V8 needs a different pump entirely. Always confirm your actual engine code rather than relying on the badge alone, as engine codes can occasionally differ from what the badge suggests.

Every internal combustion engine requires an oil pump to circulate lubricant, so an oil pump is present on all Mercedes-Benz S-Class variants regardless of whether the engine is petrol or diesel, turbocharged or naturally aspirated. What varies between variants is the specific design, dimensions, and mounting of the pump, which is why matching by engine code is essential. No S-Class variant is without one, but there is no single universal S-Class oil pump — the correct part is always engine-specific.
