Purpose and function of the actuator

The electric tailgate actuator on the right side is responsible for the controlled vertical movement of the tailgate, working in conjunction with the body electronics and other lifting mechanism components. Its placement at the rear of the vehicle on the right side allows for even load distribution, which translates into stable tailgate guidance during opening and closing. This component is particularly important in vehicles equipped with a comfort electric tailgate, where repeatability of movement, appropriate support force, and safe stopping of the tailgate in a set position are required.

Benefits of using an original actuator

Using an original actuator dedicated to the Mercedes W166 ensures:

• proper fitment to the body and tailgate mounts,
• compatibility with the factory electric control system,
• operating characteristics correctly matched to the weight of the tailgate,
• maintenance of the correct guidance axis and range of motion. As a result, the tailgate opening system retains its functionality, and the risk of overloading other mechanism components is minimized. The used part allows for an economical repair while maintaining the vehicle's original design.

Installation parameters and compatibility

The actuator is designed for installation at the rear of the vehicle on the right side, which facilitates the identification of the correct part during service. The design intended for Mercedes allows for installation in place of the factory component without the need for body or mount modifications, which shortens repair time and reduces the risk of installation errors. Selecting the correct component from this group is crucial for maintaining uniform operation of both sides of the tailgate mechanism; therefore, when replacing one of the actuators, it is worth paying attention to the compatibility of the installation side and its intended use for a specific model series.

Condition and service application

The offered actuator is a used part, which allows for a cost-effective restoration of the tailgate opening system's efficiency while maintaining the original design specifications. This type of component is suitable both for typical repairs following wear and tear and for replacement after mechanical damage to the rear of the body.

Expanding the tailgate system in a Mercedes

If you are planning a comprehensive repair or upgrade of the loading area in your Mercedes and need other elements from the same group, such as guides, hinges, or additional lifting mechanisms, check out the available parts in the Mercedes Loading tailgates category. To better plan service work within the body and comfort systems, it is also worth expanding your knowledge of other vehicle components – practical information on diagnostics and safe replacement of air conditioning system elements can be found in the article AC compressor – symptoms of failure, causes, and safe replacement.
