Purpose and function in the vehicle

The presented trunk lid lock actuator has been designed specifically for the rear of the W220 generation S-Class sedan. It is responsible for mechanical locking and releasing of the latch, working in conjunction with the factory control system and the tailgate mechanism. Thanks to the precise fit to the body structure, the correct closing geometry is maintained, which reduces the risk of play, rattling, or problems with opening the trunk.

Its location in the rear zone of the vehicle means that this component has a direct impact on the comfort of daily use – from convenient access to the cargo space to the proper operation of the central locking system and the security of transported cargo.

Compatibility and identification parameters

The actuator is a factory solution used in Mercedes S-Class W220 models, which guarantees compatibility with the original installation and the trunk lid construction. Appropriate manufacturer markings and assignment to a specific reference allow for unambiguous identification of the part and its matching to a specific vehicle equipment version.

Thanks to the presence of the OEM number and interchangeable numbers, the part can be easily verified against service documentation or the manufacturer's catalog, which minimizes the risk of purchasing an incompatible lock. If necessary, it is worth comparing the markings with the currently installed element or consulting the selection with a mechanic.

Condition, advantages, and practical application

The offered trunk lid lock actuator is a used component, which allows for an economical repair of the locking system while maintaining the manufacturer's original specifications. This type of solution is particularly beneficial for older generations of vehicles, where efficiency and compatibility are the priority, rather than purchasing a brand-new subassembly.

Replacing a faulty lock with an original salvaged actuator allows you to restore:

• proper locking of the tailgate,
• stable closing without the need for excessive force,
• cooperation with the central locking and security system,
• comfortable access to the luggage space.

Due to the preservation of the factory design, the installation proceeds in a manner similar to the service procedure provided by the manufacturer, which facilitates workshop work and reduces vehicle downtime.
