Used Mercedes-Benz B-Class Roof Panel

The B-Class runs across two well-established generations: the first generation (W245) ran from 2005 to 2011, and the second generation (W246) ran from 2012 to 2018. The roof panel is platform-specific, so a W245 panel will not fit a W246 car and vice versa – these are completely different bodies. Stick to sourcing from the correct generation and confirm the exact year with your breaker against your registration plate.

Both years fall within the second-generation W246 (2012–2018), so they share the same basic body structure, which is a good start. However, Mercedes introduced a facelift to the W246 in 2015, and there is a possibility of minor pressing changes around that point that could affect panel fit – this is something you must confirm with the breaker against your specific registration rather than assume. Always have the breaker check both donor and recipient vehicles before committing.

Trim level does not affect the fitment of a roof panel on the B-Class – the pressing is the same across SE, Sport, and AMG Line variants. You may find cosmetic differences such as a roof spoiler, aerial position, or sunroof aperture depending on optional equipment fitted to the donor car, so check those details with your breaker. As long as the generation matches, trim level alone is not a reason to reject a panel.

Yes, this matters significantly – a roof panel cut from a car with a panoramic sunroof will have a large aperture pressed or cut into it, while a standard roof is a full panel. You need to source a panel that matches your own car's specification in this regard, so tell your breaker clearly whether your car has a panoramic sunroof or not. Fitting the wrong type is not a straightforward swap and could create serious structural and weather-sealing problems.

The B-Class W246 was sold across multiple markets under the same nameplate, and while the basic body structure is shared, there can be subtle pressing or trim-fixing differences between regional variants. This is one of those specifics you should not assume – confirm with the breaker that the donor vehicle matches your UK-registered car before purchase. A reputable breaker will be able to cross-reference both registrations to check compatibility.
