Used Mercedes-Benz B-Class Rear Bumper

The Mercedes-Benz B-Class W246 generation ran from 2012 to 2018, with a facelift in 2014 that brought restyled bumpers — so a pre-facelift bumper from 2012–2014 and a post-facelift bumper from 2015–2018 are different pressings and will not swap directly. If the donor car is from the same pre- or post-facelift phase as yours, fitment is much more likely, but confirm the exact part against your registration with the breaker before buying.

No — the W245 (2005–2011) and the W246 (2012–2018) are entirely different generations with no shared body panels, so the rear bumpers are not interchangeable. Always source a bumper from the correct generation and check the facelift cut-off with the breaker to make sure you're getting the right pressing for your year.

Trim level — whether SE, Sport, AMG Line or Urban — does not change the underlying bumper shell or mounting points on the B-Class, so a bumper from any trim will physically fit your car. However, AMG Line models typically have a more aggressive lower valance and diffuser-style finish, so if you fit a bumper from a different trim you may see a cosmetic difference in the lower section — worth being aware of before you buy.

The 2016 car is a post-facelift W246 (facelift applied in 2014), while a 2012 bumper is pre-facelift, so the two are from different styling phases and are unlikely to be a clean fit. Stick to a post-facelift W246 donor from 2015–2018 for the best chance of a direct match, and confirm the part details with the breaker against your registration.

No — whether your B-Class is a petrol, diesel or electric (B 250 e), the engine has no bearing on rear bumper fitment. What matters is the generation (W245 or W246) and which side of the 2014 facelift your car sits on, so focus your search on those details and let the breaker cross-reference the part against your registration number.

The B-Class is a five-door hatchback throughout its production, so body style variation is not a concern here. However, minor pressing or trim-clip differences can sometimes exist between market variants or within a generation, so confirm the donor part against your registration with the breaker rather than assuming any same-phase W246 bumper is identical to yours.
