Purpose and function of the component

The fuel filler flap in the Mercedes S-Class W221 generation serves both a protective and aesthetic function. It secures the fuel filler area against dirt, moisture, and mechanical damage, while maintaining the continuity of the body lines. Its location in the rear part of the vehicle makes it susceptible to typical parking damage, which is why replacing it with a functional component is essential for maintaining the proper appearance of the car.

Color and paint matching

The presented flap is finished in the factory color Tanzanite Blue Metallic – 359, characteristic of elegant Mercedes W221 configurations. The metallic shade provides color depth and an attractive light effect, which is important when restoring the bodywork after body and paint repairs. Using the original color makes it easier to match the existing paint on the vehicle, reducing the need for additional painting of entire panels.

Technical characteristics and installation

The fuel filler flap is a component structurally prepared for installation at the factory mounting points in the rear part of the body. Proper edge profiling and correct geometry ensure a perfect fit with the bodywork and the fuel filler door, which translates into an even gap and correct operation of the opening mechanism. Thanks to maintaining the original specification, the installation process is predictable for an experienced mechanic or bodywork specialist.

Condition and service application

The component comes from disassembly and is intended for reuse in Mercedes W221 vehicles where the factory fuel filler flap has been damaged. It is suitable for both post-accident repairs and cosmetic body restoration, where the goal is to restore a consistent look to the rear of the car. Choosing a used OEM component allows you to maintain the original character of the vehicle at reasonable service costs.

Technical support and additional information

To correctly select a fuel filler flap for a specific car configuration, it is worth using the OEM part number and interchangeable numbers visible in the technical specification, as well as vehicle data. In case of doubts regarding compatibility with a specific body version, comparing the shape and color of the element with the currently installed flap may be helpful.
