Used Mercedes-Benz B-Class Door

The B-Class has run across two main generations: the first generation (W245) ran from 2005 to 2011, and the second generation (W246) ran from 2011 to 2018 with a facelift in 2014. Doors from the W245 will not fit a W246, and vice versa, as the body structures are different generations entirely. Within the W246, doors from before and after the 2014 facelift may differ, so if your car sits either side of that boundary, confirm compatibility with the breaker against your registration before buying.

The W246 facelift arrived in 2014, and while the basic door shell may share the same generation, there can be differences in panel detailing, trim attachments, and glass aperture around the facelift change. Whether a pre-2014 door fits cleanly on a post-2014 W246 is not something we can confirm as fact, so route this directly to the breaker with your registration to check before ordering. Colour differences are not a fitment concern, as any door can be resprayed to match.

For the W246 B-Class, trim levels such as SE, Sport, AMG Line, and Urban do not affect the basic door fitment — the door frame, shell, and hinges are the same across trims. You may receive a door with different interior trim, glass, or speaker cutouts depending on the spec of the donor car, but these are cosmetic or accessory differences rather than fitment ones. Bear in mind that features such as electric windows, heating, or mirror wiring may vary by trim, so confirm the internal specification with the breaker if those details matter to you.

In UK convention, NS (nearside) is the passenger side, which is the left side as you sit in the driver's seat, and OS (offside) is the driver's side on the right. The B-Class is a five-door hatchback, so you'll need to specify whether you want a front or rear door as well as the correct side. Give the breaker your registration and tell them NS or OS front or rear to make sure you get the right door.

Within the W245 (2005–2011) or the W246 (2011–2018), doors from the same generation are generally more likely to be compatible with one another, but small running changes can occur throughout a production run. The 2014 facelift of the W246 is the most significant boundary to be aware of, and crossing it is the point where you should be most cautious. Always confirm the donor car's exact year against your registration with the breaker before purchasing.

Engine type has no bearing on door fitment for the B-Class — petrol, diesel, and hybrid variants all use the same door structures within a given generation. Colour is purely a cosmetic consideration and does not affect whether the door fits, as any used door can be resprayed to match your car. Focus your enquiry on the correct generation (W245 or W246), the facelift year if applicable, and the right side (NS or OS) front or rear.
