Cheap Mercedes-Benz B-Class Sump

The W246 B-Class ran from 2011 to 2018, with a facelift in 2014, so both years sit within the same generation. However, the sump follows the engine code rather than the production year, so the key question is whether both cars share the same engine code — check your V5 or run a VIN check to confirm. Whether any ancillary or mounting changes were introduced at the 2014 facelift point is something you should confirm with the breaker against your registration before buying.

No — petrol and diesel sumps are not interchangeable, as the engine architecture, oil capacity, and pickup pipe position differ between fuel types. Always tell the breaker your fuel type as well as your engine code, which you can find on your V5 logbook or via a VIN check. Giving the breaker the engine code directly is the most reliable way to ensure you're quoted the correct sump.

The engine sump itself sits on the bottom of the engine block, not the gearbox, so in most cases the gearbox type does not affect sump fitment. That said, the engine code remains the primary guide, and you should confirm with the breaker if your car has an unusual drivetrain configuration. Sharing both your engine code and gearbox type when requesting a quote gives the breaker the clearest picture.

No, trim level does not affect sump fitment — the sump is determined by the engine, not whether your car is an SE, Sport, or AMG Line. These trims differ in interior specification, styling packs, and equipment levels rather than anything mechanical relating to the sump. Focus on supplying your engine code to the breaker and the trim name can be ignored entirely for this part.

Both the pre-facelift (2011–2014) and post-facelift (2014–2018) B-Class are part of the same W246 generation, so the engine code is your starting point for checking compatibility. Whether specific sump designs or ancillary mountings changed across the 2014 facelift boundary is something you should confirm with the breaker against your registration, as mid-production changes can catch buyers out. Provide your engine code and your car's registration when getting quotes so the breaker can verify the part precisely.

The single most useful detail is your engine code, which appears on your V5 certificate or can be found via a VIN check — this matters far more than the year or badge on the car. You should also tell the breaker your fuel type, year of manufacture, and gearbox type to help them narrow down the correct part quickly. Trim level and colour can be left out entirely, as neither affects sump fitment.
