Used Mercedes-Benz EQA Central Locking Motor

The EQA is a fully electric vehicle built on Mercedes-Benz's electric-first platform, and it does not use traditional vacuum or individual electric central locking motors of the type found in older or combustion-engined vehicles — the door locking system is integrated into the Body Control Module and door latch actuator assemblies rather than separate standalone central locking motors. If your EQA has a locking fault, the component you are most likely looking for is a door latch actuator (sometimes called a door lock actuator) fitted within the door latch mechanism itself. Speak to your breaker with your registration and describe the fault you have, and they will be able to identify the correct latch actuator or control module for your specific door and vehicle.

On the EQA, the locking function is carried out by a door latch actuator built into the door latch assembly, rather than a separate central locking motor, so that is the part to request from a breaker. You will need to specify which door is faulty — nearside (NS) front, offside (OS) front, NS rear, or OS rear — as each door has its own latch unit. Provide your registration to the breaker so they can match the correct latch actuator for your car.

The Mercedes-Benz EQA (H243) launched in the UK in 2021 and has remained a single-generation model; a facelift was introduced for the 2024 model year, which brought some exterior and interior updates. Whether door latch actuators interchange across the pre-facelift and post-facelift cars is not something that can be confirmed here with certainty, so you should check the part number with your breaker against both the donor and recipient registrations before buying. This is especially important for the post-2024 facelift cars.

Trim level — whether your EQA is in AMG Line, AMG Line Premium, or AMG Line Premium Plus specification — does not affect the door latch actuator required, as the locking mechanism is the same across trim grades. You may find cosmetic differences when removing door cards, such as different upholstery or speaker finishes, but the latch unit itself is a mechanical and electrical component unaffected by trim. Confirm the correct part with your breaker using your registration rather than trim name alone.

The EQA and EQB share the same H243/H247 platform and were developed together, so there is a possibility that some latch components are shared, but this cannot be stated as fact here. You should provide your breaker with the registrations of both vehicles and ask them to cross-reference the part numbers before purchasing. Do not assume cross-model compatibility without that confirmation.
