Application and vehicle function

The offered fuel filler flap is dedicated to the rear body section of Mercedes W204 class models. It is responsible for covering the fuel filler neck, protecting the refueling area from contaminants and weather conditions, while maintaining the body styling line consistent with the manufacturer's design.

This component is particularly useful for post-accident repairs, replacement after parking damage, or in situations where the existing flap shows clear signs of wear. Thanks to its factory origin, it ensures proper fitment to the body and correct operation with the opening and closing mechanism.

Color and paint matching

The flap is finished in the Alabandine Grey Metallic - 779 shade, which allows for consistency with the vehicle's original paint in this color. The metallic coating provides the characteristic depth and light reflections typical of factory Mercedes paints, which is important both for aesthetic reasons and for potential body and paint repairs.

In the case of professional body restoration or local painting, using a flap in the correct color code limits the scope of corrective work and makes it easier to achieve an even transition between body panels.

Product characteristics and condition

This is a used part, sourced from dismantling, which allows you to combine original quality with a more favorable purchase cost compared to brand-new components. Such parts are often chosen for economic repairs, where maintaining the OEM standard while optimizing the service budget is a priority.

Thanks to its factory construction, the flap retains the correct geometry, mounting points, and shape tailored to the W204 body line, which translates into proper alignment with the fender and other body panels.

Benefits of using an original fuel filler flap

Choosing an original fuel filler flap for the Mercedes W204 in Alabandine Grey Metallic brings a number of practical advantages:

• maintaining the factory look of the rear body section without the need for installation modifications,
• color consistency with the vehicle's paint in code 779,
• compatibility with the standard opening and closing mechanism,
