Mercedes-Benz CLA Window Motor Replacement Parts

The CLA has had two distinct generations: the first generation (C117) ran from 2013 to 2019, and the second generation (X118/C118) launched in 2019 onward, so motors from a first-gen car are very unlikely to fit a second-gen and vice versa. Always tell the breaker which generation your car is — your registration will confirm this instantly. Cross-generation fitment is not advisable without the breaker checking the part numbers against your specific vehicle.

Yes, side matters significantly — the nearside (NS, passenger/left) and offside (OS, driver/right) motors are not interchangeable, and you must specify which door you need. Within the same generation, front and rear door motors are also different units, so be clear whether you need a front or rear door motor as well. Always state NS or OS and front or rear when requesting a quote from a breaker.

The 2017 and 2014–2015 cars are all first-generation CLA (C117), which ran from 2013 to 2019, so they share the same basic body structure and door configurations. For motors on the same side and door position within that generation, fitment is generally consistent, but confirm with the breaker against your registration to be sure no mid-run changes affect your specific car. Providing your reg to the breaker is the safest way to get the right part.

Trim level — whether SE, Sport, AMG Line, or any other — does not affect the window motor itself, as the door structure and motor mount are the same across trims within the same generation. You may find cosmetic differences in the door panel or trim finishers when fitting a door card from a different trim car, but the motor is a mechanical fitment concern, not a cosmetic one. Focus on getting the correct generation, side, and door position rather than matching trim level.

The CLA Shooting Brake (estate-style body, X117 in the first generation, C118 estate in the second) has different rear door and body structures compared with the standard CLA saloon/coupe body, so rear door motors from a Shooting Brake are unlikely to be compatible with a standard CLA. Front door motors may share more in common, but this is still something to confirm with the breaker against both vehicles' registrations rather than assume. Always specify which body style your car is when requesting a quote.

The first-generation CLA (C117) received a facelift around 2016, which brought cosmetic updates but did not substantially change the door structure or window motor specification. Motors from pre- and post-facelift first-gen cars are likely compatible for the same side and door position, but given that minor production changes can occur, it is best to confirm with the breaker using both vehicles' registrations before purchasing. Stating your exact reg ensures the breaker can verify part numbers and advise with confidence.
