Used Mercedes-Benz B-Class Bumper

The first-generation B-Class W245 ran from 2005 to 2011 with a facelift arriving in 2008, which updated the front bumper, grille and lights. Any pre-facelift bumper (2005–2008) should swap directly with another from the same pre-facelift period, and the same applies within the post-facelift range (2008–2011). If you're trying to cross that 2008 facelift boundary, confirm with the breaker against your registration before buying.

The second-generation B-Class W246 ran from 2011 to 2018, with a facelift in 2015 that brought revised front and rear bumpers along with updated lighting. Bumpers from within the pre-facelift period (2011–2015) generally interchange with one another, as do those within the post-facelift period (2015–2018). If a bumper spans that 2015 boundary, check with your breaker quoting your registration to confirm whether it will fit your specific car.

These two cars sit on the same W246 platform, but they fall either side of the 2015 facelift, which is the key boundary where bumpers and front-end panels typically changed. Because one is pre-facelift and one is post-facelift, fitment across that boundary is not straightforward. Confirm with the breaker against both registrations before proceeding.

Trim level does not affect which bumper fits in a mechanical sense; what matters is the generation (W245 or W246) and whether both cars are the same side of the facelift boundary. However, the AMG Line trim uses a different-looking bumper with more aggressive styling and different lower apron detailing compared with SE or Sport, so fitting a bumper from a different trim will change the appearance of your car. If you're happy with that cosmetic difference there's no fitment barrier, but make sure you're buying from the same generation and facelift period.

Engine choice makes no difference to bumper fitment on the B-Class; the front and rear panels are shared across petrol and diesel variants within the same generation and facelift period. Just match the generation (W245 2005–2011 or W246 2011–2018) and confirm which side of the facelift boundary your car sits on. A breaker can cross-reference your registration to make sure the part they have matches your exact vehicle.

The most reliable approach is to ask the breaker to check the donor car's registration against yours, as this will confirm the generation and facelift period rather than relying on an approximate year. For the W246, the critical question is whether the donor car is pre- or post-2015 facelift, since bumpers changed significantly at that point. Never rely on year alone, as build dates and registration dates can straddle a facelift boundary, so always have the breaker verify against the actual registration.
