Purpose and function in the vehicle

The hydraulic tailgate pump in Mercedes W164 series SUV models is responsible for generating pressure in the system that controls the movement of the rear lid. This component operates in the rear body section, working in conjunction with actuators and the control installation, which allows for smooth opening and closing of the trunk lid.

A properly selected pump is crucial for:

• maintaining the correct speed of the lid movement,
• ensuring repeatable system operation under various operating conditions,
• reducing mechanical loads acting on hinges and mounts.

Benefits of using an original hydraulic pump

Using an original component dedicated to Mercedes allows for maintaining the factory performance parameters of the tailgate lifting system. The pump is designed to work with the existing hydraulic and electrical installation, which facilitates installation and reduces the risk of compatibility issues.

The main advantages include:

• Factory fitment to the tailgate structure and body system,
• stable operation within typical load ranges for Mercedes W164 vehicles,
• the ability to restore the correct operation of the automatic or assisted trunk opening after the failure of the old unit.

Characteristics and installation in the rear of the vehicle

The pump is designed for installation in the rear zone of the vehicle, in the immediate vicinity of the tailgate system. Its design allows for integration with factory hydraulic lines and mounts provided by the vehicle manufacturer. Thanks to this, the replacement process can be carried out in an orderly manner, maintaining the original routing of lines and mounting points.

The component comes from the used Mercedes parts group, which allows for an economical repair of the tailgate lifting system while maintaining the original design specifications. Before installation, it is recommended to perform a standard inspection of the hydraulic system and the condition of the lines to ensure the proper operation of the entire system.

Application in service practice

Replacing the hydraulic pump is a typical service procedure in the event of symptoms such as slowed lid operation, lack of response to opening commands, or uneven movement of the lid. Using an original component allows for restoring trunk functionality without the need for interfering with the body structure.

In workshop practice, the following are particularly appreciated:

• compatibility with the factory tailgate control,
• the ability to use existing mounting points,
• maintaining the operating parameters of the system as intended by the manufacturer.
