Second Hand Mercedes-Benz X-Class Central Locking Motor

Yes, the X-Class does use central locking motors — typically one per door — as part of its central locking system, so this is a genuine part you can source from a breaker. The X-Class was sold in the UK from 2017 to 2020, and all variants used an electrically operated central locking system. If your locking is behaving erratically or a single door is failing to lock or unlock, a faulty door lock actuator (central locking motor) is a common culprit.

The Mercedes-Benz X-Class had a single, relatively short production run in the UK covering 2017 to 2020, and there was no major structural or electrical architecture change within that period that is known to affect door lock actuator fitment. On that basis, a motor from a 2017 car is likely compatible with a 2019 car, but because door latch and actuator assemblies can vary by door position (front NS, front OS, rear NS, rear OS), make sure you match the exact door position when ordering. Confirm the part number with the breaker against your registration before purchasing to be sure.

Trim level does not affect which central locking motor you need — the door lock actuator is part of the core locking system fitted across all X-Class variants regardless of whether the car is a Pure, Progressive, or Power spec. What matters is the door position (front or rear, nearside or offside), so tell the breaker which door is faulty rather than which trim you have. You may find higher-spec cars have additional features like soft-close or memory mirrors, but the central locking motor itself is not a trim-specific component.

No — the drivetrain layout of the X-Class (whether it is the rear-wheel-drive or the 4MATIC four-wheel-drive variant) has no bearing on the door lock actuators, which are part of the body electrical system rather than the drivetrain. You should focus on matching the correct door position (NS front, OS front, NS rear, OS rear) and confirming the part fits your specific registration with the breaker.

The X-Class shares its underpinnings with the Nissan Navara and Renault Alaskan, and some mechanical components do interchange between these platforms, but door lock actuators are more closely tied to the body shell, door design, and wiring loom of the specific vehicle. It is not safe to assume a Navara or Alaskan actuator will drop straight in, even if the doors look visually similar. Put this question directly to the breaker and provide your X-Class registration so they can check part numbers before you commit to buying.

A faulty central locking motor typically affects one door only, causing it to fail to lock or unlock while the rest of the car operates normally — that pattern points strongly to the actuator on that specific door. If all doors fail at once, or the locking behaves inconsistently across the whole car, the fault is more likely to be in the key fob, the body control module (BCM), or the wiring rather than an individual motor. It is worth having the car scanned for fault codes before buying a used part, as this will help you and the breaker pinpoint exactly what needs replacing.
