Purpose and function of the trunk drainage trim

The trunk drainage trim in the Mercedes W164 is responsible for directing water and debris away from the rear edge of the body, which reduces the risk of moisture entering the cargo area. The component is mounted in the rear left part of the vehicle, working in conjunction with seals and other trunk assembly components.

A correctly selected trim:

• stabilizes water flow along the trunk edge,
• supports the tightness of sheet metal and upholstery joints,
• reduces dirt accumulation in critical areas,
• maintains a consistent look of the body line on the left rear side of the vehicle.

Fitment for Mercedes W164 and mounting parameters

The offered trim has been designed specifically for the Mercedes W164 body structure, which translates into precise fitting with factory mounting points. Its placement in the rear left part of the vehicle allows for seamless integration with existing trunk elements, without the need for body modifications.

Key mounting features:

• dedicated position in the rear zone on the driver's side,
• compatibility with the factory geometry of the trunk edge,
• preservation of the original body line after installation.

Characteristics of the used component

The trim comes from disassembly, which means it is an original Mercedes brand component with a construction consistent with factory standards. A used element allows for an economical repair or replacement of a missing trim while maintaining consistency with other body parts.

Choosing a trim from disassembly is a solution that:

• allows you to maintain the original character of the trunk finish,
• is cost-effective compared to new replacements,
• supports the reuse of functional structural components.

Practical application and benefits of replacement

Replacing a damaged or missing trunk drainage trim on the left rear side of the vehicle helps restore the correct water drainage direction and the aesthetics of the loading edge. This is particularly important in cases of intensive vehicle use, frequent opening of the trunk lid, or use in difficult weather conditions.

The main benefits of installation include:

• reducing the risk of dampness in the trunk upholstery,
• limiting corrosion in the loading edge area,
• maintaining an even finish line on the left rear side of the car,
• preserving visual consistency with other Mercedes body elements.
