Purpose and function of the component

The presented cover is a part from the Tailgates and rear parts group, mounted in the rear zone of the vehicle. Its task is to cover the tailgate lock, protect the mechanism against accidental mechanical damage, and visually organize the luggage space. Thanks to its fitment to the Mercedes ML W166 body structure, the element ensures stable mounting and correct alignment of the upholstery edges in the lock area.

Construction, color, and fitment

The lock cover is manufactured as a dedicated component for the rear body section, with profiling that matches the geometry of the tailgate in the ML W166. The black color facilitates integration with the factory upholstery and trunk plastics, reducing the visibility of any potential operational scratches. The element is intended for installation in the rear part of the vehicle, which allows for precise fitting with the lock and other interior covers.

Use in service and repairs

The tailgate lock cover will prove useful for:

• restoring the completeness of the tailgate after body and paint repairs,
• replacing missing finishing elements in the luggage space,
• improving the aesthetics of the rear interior after previous disassembly,
• servicing the lock mechanism when it is necessary to replace a damaged cover.

As a dismantled part, the element allows for an economical restoration of the factory look of the tailgate, while maintaining compliance with the solutions used by Mercedes in the ML W166 model.

Benefits of using an original cover

Using a dedicated lock cover in the rear body section ensures:

• a visually consistent look of the luggage space,
• protection of the lock mechanism against accidental impact from luggage,
• easier maintenance of order in the area of the lock and upholstery,
• secure fitment to the tailgate structure in the ML W166 without modifications.

For users who pay attention to technical correctness and finishing aesthetics, the original rear lock cover is a reasonable choice for any major intervention in the rear part of the body.

Part selection and additional information

When selecting tailgate finishing elements, it is worth verifying compatibility with the specific version of the ML W166 body and the existing upholstery configuration. Manufacturer markings, reference numbers, and mounting parameters assigned to a given unit can be helpful. In case of doubts regarding compatibility, it is recommended to consult a service center specializing in the Mercedes brand or compare with currently installed components.
