Cheap Mercedes-Benz C-Class Oil Pump

This crosses from the W203 generation (2000–2007) into the W204 generation (2007–2014), and oil pumps are engine-specific, so the answer depends entirely on whether both cars share the same engine code rather than just the same badge. If you and the breaker have matching engine codes (for example, two cars both running the 271 four-cylinder petrol), there may be compatibility, but the generation change means ancillary differences are likely. Always confirm against both registration numbers with the breaker before buying.

The W204 ran from 2007 to 2014 and the W205 from 2014 onwards, and while some engine families carried across that boundary, Mercedes revised ancillary components between generations. The engine code is the key detail here — if both cars share the exact same engine code, there is a stronger chance of compatibility, but you should confirm with the breaker against both registrations rather than assume the part crosses over safely.

Yes — the oil pump is driven directly off the engine's internal architecture, so a matching engine code is far more reliable than a matching year or model badge. Two C-Class cars from the same year can carry completely different engines and completely incompatible oil pumps, while a car from a different year with the same engine code is a much stronger match. Your engine code is on your V5C or available via a VIN check, and giving it to the breaker is the single most useful thing you can do.

No — SE, Sport, AMG Line and AMG trim levels describe interior and exterior specification rather than the engine internals, and the oil pump follows the engine code, not the trim badge. Two W205 C220d cars, one SE and one AMG Line, running the same OM651 or OM654 engine code will use the same oil pump. The only trim-related question worth asking is whether an AMG variant (such as a C43 or C63) carries a different engine entirely, in which case the engine code will make that obvious.

Yes, absolutely — diesel and petrol engines are entirely different units with different oiling systems, and their oil pumps are not interchangeable under any circumstances. When searching, always filter by fuel type as well as engine code, and make sure the breaker is quoting for a part from a matching engine rather than just a matching model year. Giving the breaker your exact engine code removes any ambiguity about fuel type.

The W204 received a facelift around 2011, but whether this affects the oil pump depends on whether your specific engine code changed or was revised at that point — the bodywork and interior updates do not in themselves mean the oiling system changed. For many engine codes the pump remained the same across the facelift, but Mercedes did introduce updated engine variants during the W204's life, so you cannot assume a pre-facelift and post-facelift pump are identical without checking. Confirm with the breaker by providing your engine code and registration so they can verify the correct part.
