Second Hand Mercedes-Benz A-Class Oil Pump

The A-Class has run across four main generations — the W168 (1997–2004), W169 (2004–2012), W176 (2012–2018, with a facelift around 2015), and W177 (2018–present) — and the oil pump is tied directly to the engine code, not the generation badge, so crossing any of these generation boundaries is very unlikely to produce a compatible part. Each generation introduced entirely different engine families with different block architectures, meaning a pump designed for one generation's engine will almost certainly not suit another's. Always supply your exact engine code — found on your V5 or via a VIN check — when requesting quotes from a breaker, as this is the single detail that determines compatibility.

No — petrol and diesel engines are fundamentally different units with different blocks, oil circuits, and pump designs, so the fuel type is a hard fitment boundary even within the same model year and generation. A W176 petrol engine code such as the M270 will use a completely different oil pump to a W176 diesel such as the OM607 or OM651. Always confirm your fuel type and engine code with the breaker so they can match the pump to your exact engine, not just your model year.

The W176 received a facelift in 2015 that was largely cosmetic, but some engine variants were revised or carried over, and whether the oil pump changed mid-production is something you should confirm with the breaker against your exact registration and engine code rather than assume from the facelift year alone. If you and a donor car share the same engine code, there is a much stronger basis for compatibility, but ancillary or mounting changes within a production run can catch buyers out. Give the breaker both your registration and engine code so they can cross-reference accurately.

Trim level — whether SE, Sport, AMG Line, or any other — makes no difference to oil pump fitment, as the pump is determined entirely by the engine, not by the badge or interior specification. An A200 Sport and an A200 AMG Line with the same engine code will use exactly the same oil pump. When buying used, be aware that parts pulled from different trim cars may have superficial cosmetic differences on surrounding components, but the pump itself is an engine-matched mechanical part, so trim is irrelevant.

The gearbox type does not directly change the engine oil pump, as that pump serves the engine lubrication circuit regardless of whether the gearbox is a 7G-DCT automatic or a manual. However, some automatic transmissions have their own separate transmission oil pump, which is a different part entirely — so make sure you are clear with the breaker whether you need the engine oil pump or a gearbox-related pump. Confirming your engine code alongside the gearbox type will help the breaker supply exactly the right component.

This is possible in some cases because the A-Class, B-Class, and CLA have shared engine families — for example, the M270 four-cylinder petrol engine was used across all three in the W176/W246/C117 era — meaning the oil pump may be identical if the engine codes match exactly. However, you should not assume compatibility based on the model name alone, as spec variations and running changes can result in differences even between cars using broadly the same engine family. Provide the breaker with your full engine code and ask them to verify against the donor vehicle's engine code before purchasing.
