Purpose and function in the vehicle

The automatic closing motor operates in the rear part of the body, in the trunk lid area, responsible for mechanically pulling the lid shut after the process is initiated by the user or the vehicle system. This element works with the body control module, position sensors, and the latch, ensuring:

• controlled movement of the lid in the final closing phase,
• stable closing without the need for excessive force,
• consistent operation with factory comfort systems in the X218 CLS-Class model.

Thanks to this solution, operating the rear part of the vehicle is more ergonomic, especially in daily urban use and when frequently accessing the luggage compartment.

Compatibility and integration with the vehicle system

The motor has been designed for integration with the factory trunk lid control system in the X218 CLS-Class model, maintaining the parameters specified by the manufacturer. Proper fitment within the Trunk lids and rear parts category allows for correct cooperation with:

• the hinge and guide mechanism of the lid,
• the latch and striker assembly,
• the electrical installation controlling the lid movement.

Its location in the rear of the vehicle facilitates direct torque transmission to the lid mechanism, which reduces energy loss and improves operational consistency over a long service life.

Performance characteristics and installation benefits

The offered trunk lid automatic closing motor is a component intended for reinstallation in the vehicle, replacing the factory part with an identical function. Using an original Mercedes solution allows you to maintain:

• operational consistency with existing body electronics,
• appropriate speed and closing force characteristics,
• factory-standard operation of the tailgate system.

Replacing a worn or damaged motor with the presented component helps restore the proper function of the automatic closing feature, eliminating issues such as the lid failing to close, stopping mid-travel, or the need for manual pulling.

Component condition and installation aspects

The product is offered as a used part, which allows for an economical repair of the tailgate system while maintaining the original design. During installation, it is recommended to:

• check the correctness of the mounts in the rear body area,
• verify the condition of the electrical wiring in the lid area,
• perform an adaptation or functional test in the vehicle's diagnostic system after installation.

This approach facilitates the restoration of full system functionality without the need to interfere with other rear body components.
