Purpose and function of the component

The described rear left door window moulding has been designed as a factory body component for the ML W164 series. Its function is to:

• protect the window edge and the adjacent door section from external factors,
• provide stable guidance for the seal and maintain the correct window contact line,
• complement the side styling of the body in accordance with the manufacturer's design.

Thanks to its precise profile, the moulding works in harmony with the door structure and the window, reducing the risk of unwanted wind noise and improving the overall refinement of the vehicle.

Color and visual fitment

The element is finished in Tanzanite Blue Metallic - 359, which allows for maintaining paint consistency with a body in this color without the need for additional painting. The metallic finish ensures:

• harmonious integration of the moulding into the vehicle's side line,
• an aesthetic transition between the window and the door surface,
• preservation of the original stylistic character of the ML W164 series.

For users who care about the visual continuity of body components, this is a solution that allows for a technically correct replacement without compromising on appearance.

Vehicle placement and installation aspects

The moulding is intended for installation in the rear area, on the left side, on the door with a side window. The precisely defined vehicle placement facilitates the selection of the correct component for accident repairs or the replacement of worn parts. The original geometry of the part promotes:

• proper fitment with the edge of the window and door,
• preservation of factory gaps and body lines,
• reduction of time required for adjustment during installation.

The product comes from a used vehicle, which is important when selecting parts with a similar degree of wear to other body components.

Operational characteristics and benefits of use

Using this moulding in a Mercedes ML W164 allows for the restoration of proper window edge protection and the aesthetics of the side body section. Key benefits include:

• factory origin – compliance with the manufacturer's design and predictable performance in operation,
• dedicated placement – no need for modifications to the door structure,
• preservation of the original stylistic line – especially important for accident repairs and restorations.

For body shops and individual users, this means the possibility of performing repairs in a manner close to the factory standard, while maintaining visual and functional consistency.
