Cheap Mercedes-Benz B-Class Door Hinge

The Mercedes-Benz B-Class W246 generation ran from 2012 to 2018, with a facelift in 2014, so a 2012 and a 2016 car are both W246 but sit either side of that facelift boundary. Hinges are side-specific (NS or OS) and the structural mounting points are generally consistent across the W246 generation, but whether the facelift changed hinge dimensions or fixing points on your specific door should be confirmed with the breaker against both registrations before buying. Never assume fitment without that check.

No — the W245 (2005–2011) and W246 (2012–2018) are different generations with different body structures, so their door hinges are not interchangeable. Always source a hinge from the correct generation for your car, and quote your registration to the breaker so they can verify the exact match. Mixing generations on structural door components is not advised.

Yes, this matters every time — NS (nearside, passenger/left) and OS (offside, driver/right) hinges are mirror-image components and are not interchangeable. Always tell the breaker which side you need, and double-check whether you need the upper or lower hinge for that door, as most doors carry two. Ordering the wrong side will mean the hinge simply will not fit.

No, the trim level does not affect door hinge fitment on the B-Class — the hinge is a structural body component that is the same regardless of whether your car is SE, Sport, or AMG Line. What does matter is the generation (W245 or W246) and the side (NS or OS). You may find cosmetic differences between donor and recipient cars such as paint colour, but hinges can be resprayed to match and colour has no bearing on fitment.

Both cars are within the W246 generation (2012–2018, facelifted 2014), which gives a reasonable basis for compatibility, but whether Mercedes changed hinge specifications or aperture geometry at the 2014 facelift is something you should confirm with the breaker against both registration numbers. Specify the side (NS or OS) and whether it is an upper or lower hinge when asking. Do not rely on generation alone when crossing a facelift boundary for a structural part.

Yes — engine choice has no bearing on door hinge fitment on the B-Class, as the hinge is part of the body structure and is identical across petrol, diesel, and electric variants within the same generation. The details that matter are the generation (W245 2005–2011 or W246 2012–2018), the door side (NS or OS), and upper or lower position. Confirm these details with your breaker alongside your registration to make sure you get the right part.
