Second Hand Mercedes-Benz B-Class Wiper Motor

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 arriving in 2014. The wiper motor design differs between these generations, so you must match your car's generation — W245 or W246 — when sourcing a used unit. Confirm the generation with the breaker against your registration to be sure.

Both a 2013 and a 2016 B-Class fall within the second-generation W246, but the 2014 facelift is the boundary between early and late W246 models, and wiper motor designs can differ across that facelift point. You should confirm with the breaker whether the specific part number from the 2013 car crosses that 2014 boundary and suits your post-facelift 2016 car. Never assume fitment without checking against your registration.

Trim level does not affect wiper motor fitment — the motor is determined by the generation (W245 or W246) and whether it is the front or rear unit, not by whether the car is SE, Sport, or AMG Line. You may find minor cosmetic differences in wiper arm finish between trim levels, but the motor itself should be the same within the same generation. Confirm against your registration with the breaker before purchasing.

The W245 and W246 are distinct generations with different body structures, so a wiper motor from the first generation is very unlikely to be a straight fit on the second generation. The 2011 changeover is a firm boundary here, and we would not treat these as interchangeable. Route this question to the breaker with both registrations so they can check part numbers directly.

Yes — front and rear wiper motors are completely different parts with different fittings, locations, and connectors, so you must specify which one you need when contacting the breaker. The B-Class is a hatchback with a rear wiper as standard, so both front and rear units are commonly available from dismantlers. Always state front or rear clearly alongside your registration when requesting a quote.

Motors from within the same W246 generation are more likely to be compatible with each other than those crossing into a different generation, but the 2014 facelift may have brought running changes that affect fitment. We cannot state as fact that all W246 years interchange freely, so confirm with the breaker using both the donor car's registration and your own. A good breaker will cross-reference part numbers before supplying.
