Mercedes-Benz B-Class Engine Mount Replacement Parts

The B-Class W246 generation ran from 2011 to 2018, with a facelift in 2015, so a 2013 and a 2016 car sit either side of that facelift boundary. Whether the engine mount crosses that boundary depends heavily on your exact engine code, as Mercedes made running changes to powertrains around the facelift period. Name the boundary, then confirm directly with the breaker against both registration numbers before buying.

Yes, the engine code is the single most important detail for engine mount fitment — it matters more than the year or badge, because Mercedes fitted several different four-cylinder petrol and diesel engines to the W246 B-Class across its life, and mounts are matched to the engine unit and its position in the bay. Your engine code is on your V5 logbook or can be pulled from a VIN check. Supply it to the breaker and ask them to match against it specifically.

No — trim level does not affect engine mount fitment on the B-Class at all, because mounts are a mechanical component tied to the engine and gearbox, not to the trim specification. A Sport, SE, or AMG Line car with the same engine code will use the same mount, though you may notice cosmetic differences in what surrounds the engine bay when the breaker removes the part. Focus on matching engine code and gearbox type rather than trim name.

Yes, fuel type matters because the engine units differ between petrol and diesel variants, and the mounts are designed around the specific engine block and its weight and torque characteristics. A mount from a diesel B-Class should not be assumed to interchange with one from a petrol car even of the same year. Always tell the breaker your fuel type alongside your engine code to ensure the correct mount is supplied.

Gearbox type can affect engine mount fitment because the drivetrain configuration influences how the powertrain is supported and positioned, so a mount from a manual car is not automatically interchangeable with one from a car fitted with Mercedes' 7G-DCT dual-clutch automatic. Confirm your gearbox type with the breaker alongside your engine code, and ask them to verify the part number matches before you commit to a purchase.

Both a 2011 and a 2014 B-Class sit within the same W246 generation, which ran from 2011 through to the 2015 facelift, so there is a reasonable chance of compatibility if the engine codes match. However, Mercedes did make ancillary and mounting changes at various points during production, and whether those affect this specific mount mid-generation is something to confirm with the breaker against both registration plates rather than assume. Match engine codes first, then let the breaker verify before purchasing.
