Purpose and Function of the Trunk Lid Hinge

The presented hinge has been specifically designed for the rear left side of the body in W169 series models, ensuring proper guidance of the trunk lid throughout its entire range of motion. It is responsible for:

• maintaining the correct pivot axis of the lid,
• stable opening and closing without unwanted play,
• precise alignment of the lid edges with the body panels.

Thanks to the element's factory geometry, it is possible to maintain appropriate gaps between the lid and the fenders and bumper, which reduces the risk of paint rubbing and accelerated corrosion.

Color and Visual Fit

The hinge is finished in the Horizon Blue Metallic - 391 color, characteristic of selected Mercedes paint configurations. For vehicles in the same shade, this means the possibility of an aesthetically pleasing fit without the need for additional painting in this color.

For other body colors, the hinge can serve as a solid base for repainting, while maintaining the original structure and material quality. This allows for economical repair of the rear body section after mechanical damage or corrosion.

Mounting and Operational Characteristics

The original design of the trunk lid hinge for the Mercedes W169 has been developed for durable performance in demanding operating conditions. The element is adapted to work with the factory mounting of the lid and body, which facilitates installation and subsequent adjustment.

• Compatibility with factory mounting points on the rear left side of the body.
• Precise adjustment of the lid's position relative to the car body.
• Stable operation with frequent opening and closing of the trunk.

By maintaining the original hinge geometry, the time required for lid adjustment after bodywork repair or part replacement can be reduced.
