Used Mercedes-Benz B-Class Bulkhead

The B-Class has run in two generations: the first-generation W245 from 2005 to 2011, and the second-generation W246 from 2011 to 2018 with a facelift in 2014. These two generations are built on entirely different platforms, so a W245 bulkhead will not cross to a W246 and vice versa. Always quote your generation or registration to the breaker so they can pull the right shell.

Both sit within the W246 generation and share the same fundamental platform, but mid-generation pressing changes around the 2014 facelift mean subtle panel differences can exist on a structural component like the bulkhead. Name the W246 boundary to the breaker and ask them to confirm the pressing matches your specific registration before you commit. We cannot guarantee fitment across that facelift year.

No – engine and trim choice make no difference to bulkhead fitment on the B-Class. The bulkhead is determined by the body structure, so a 180d diesel shell and a 200 petrol shell of the same generation will use the same pressing. You only need to match the generation (W245 or W246) to find a compatible unit.

Trim level does not affect bulkhead fitment; the structural shell is the same across SE, Sport, Urban, and AMG Line variants within the same generation. You may find minor cosmetic or wiring-bracket differences between trims when you're fitting the part, but these are not a reason to reject a unit from a different trim car. Confirm the generation with the breaker, and the trim on the donor car is irrelevant to structural fit.

No – the W245 and W246 are completely different platforms with different body structures, so the bulkheads are not interchangeable. You must source a bulkhead from within the correct generation for your car. Give the breaker your registration and they can verify the exact platform before pulling stock.

The B-Class was sold exclusively as a five-door hatchback throughout both the W245 and W246 generations, so there are no body-style variants to navigate within this model. What still matters is matching the correct generation – W245 (2005–2011) or W246 (2011–2018) – and checking with the breaker on any mid-generation pressing changes around the 2014 facelift. Confirming against your registration remains the safest step.
