Used Mercedes-Benz CLA Oil Pump

Every petrol and diesel engine fitted to the CLA has an oil pump — it is a fundamental engine component that circulates oil around the engine regardless of fuel type or drivetrain layout, so all CLA variants across both generations are fitted with one. However, the specific pump fitted varies by engine code, so the correct used unit depends on which engine your car has rather than simply which model it is. Check your V5 or run a VIN check to get your engine code before searching.

The C117 and C118 are substantially different cars built on different platforms and sharing no engine-bay architecture, so an oil pump from a C117 should not be assumed to fit a C118 even if both cars carry a similar badge such as CLA 200 or CLA 220d. The engine families were updated between generations, meaning the pump design, mounting, and dimensions are likely to differ. Always match by engine code — confirm the code from your V5 and ask the breaker to verify the donor vehicle carries the same code before buying.

Yes, fuel type matters significantly because petrol and diesel engines are entirely different internally, and the oil pump is engineered to suit each engine's specific pressures, outputs, and mounting arrangement. For example, a pump from a 2.0-litre diesel OM651 engine is not interchangeable with one from a 2.0-litre petrol M270 engine even though both may sit in a C117 CLA of similar age. Always identify your engine code — printed on the V5 or obtainable via a VIN check — and give that to the breaker rather than relying on engine size or fuel type alone.

Trim level makes no difference to the oil pump whatsoever — AMG Line, Sport, and SE are specification packages relating to interior, exterior, and equipment, not to the engine internals. What determines the correct pump is your engine code, which is shared across trim levels fitted with the same engine. You may find cosmetic differences between cars from different trim levels when collecting a part from a breaker, but the pump itself is determined entirely by engine code and not by badge.

The C117 received a facelift in 2016 that brought styling and equipment updates, but the core engine families carried over, meaning the oil pump is driven by engine code rather than pre- or post-facelift status. However, it is possible that ancillary or mounting details changed quietly during the production run, which can occasionally affect how a pump fits or connects. Name the boundary to your breaker — tell them your exact engine code and year — and ask them to confirm the donor pump is from a car with the same code before proceeding.

The CLA shares engine families with the A-Class, B-Class, and GLA of the same era, all built on the MFA platform, so it is plausible that a matching engine code in a donor car from one of those models could yield a compatible pump. Engine code is the key — if the donor and your CLA share the identical code, the core pump is far more likely to be correct than if you match by model name alone. That said, confirm with the breaker that there are no application-specific mounting or ancillary differences on your particular vehicle before buying.
