Purpose and function of the component

The presented fuel filler flap is dedicated to the rear body section of the Mercedes W176 class, where it is responsible for covering the fuel filler neck and maintaining the continuity of the side line. This component serves both a protective and visual function – it secures the fuel filler area against contaminants while maintaining a consistent body appearance.

Thanks to its factory geometry, the cover works with the standard hinge and opening mechanism, which facilitates installation and reduces the need for additional bodywork adjustments.

Color and paint finish

The cover is finished in Mountain Grey Metallic – 787, characteristic of the Mercedes paint palette. The metallic structure of the coating ensures uniform light reflection, which is essential for matching existing body panels.

In practice, this means the component can be used as a replacement for a damaged flap in vehicles with the same paint code, often without the need for full repainting of the entire element, provided the condition of the coating is acceptable relative to the rest of the bodywork.

Installation and operational characteristics

The fuel filler flap is adapted for installation in the rear of the vehicle, in the factory location, using standard mounting points. The OEM design allows for:

• maintaining correct geometry relative to the fender and bumper,
• compatibility with the original opening mechanism,
• maintaining the seal of the fuel filler area.

The used condition means the component comes from disassembly, which for many users is a beneficial compromise between cost and maintaining the original build quality characteristic of the Mercedes brand.

Application in body repairs

A fuel filler flap in the correct color is particularly useful for post-accident repairs and spot body corrections when only the flap or its immediate area has been damaged. Using an original component with Mountain Grey Metallic – 787 paint allows for limiting the scope of paint work and shortening the time required to restore the vehicle to an aesthetic condition.

In the case of more extensive body and paint work in the rear section of the vehicle, a matched fuel filler flap helps maintain color consistency between adjacent panels, which is important both visually and for potential vehicle resale.

Technical support and knowledge about the fuel system

To better plan work within the refueling system – from the flap, through the cap, to the tank – it is worth using technical materials describing the construction and operation of the entire system. Practical information on diagnostics, component selection by manufacturer markings, and operating principles can be found in the article "Fuel system – injectors, pumps, and fuel tank: maintenance and regeneration".
