Intended Use and Function of the Part

The fuel filler flap cover on the Mercedes W221 model is responsible for protecting the filler neck from contamination and weather conditions, while also being a visible part of the rear bodywork. A correctly chosen flap:

• protects the fuel filler area from water, salt, and road dirt,
• reduces the risk of corrosion around the fuel cap and filler socket,
• maintains a cohesive appearance of the side-rear body section,
• ensures the proper operation of the filler opening mechanism.

Flint Grey Metallic - 368 Color and Visual Matching

The presented flap is finished in the Flint Grey Metallic - 368 shade, factory-applied to selected W221 generation S-Class models. This allows for a uniform paint surface along the entire length of the vehicle's side when correctly matched to a specific car, without visible tonal differences.

The metallic paint finish fits well with the character of a luxury limousine, and proper fitment of the part with the bodywork allows for maintaining the line of creases and gaps at the factory level. This is particularly important for accident repairs and restoring the vehicle to its original manufacturer's specification.

Vehicle Placement and Installation Aspects

The cover is designed for installation in the rear of the car, in the fuel filler area. The OEM construction allows for the use of factory mounting points and cooperation with the original flap opening and closing mechanism. When correctly matched to a specific Mercedes W221 model, installation is similar to plug-and-play, without the need for body modifications.

As a used part, the flap is a cost-effective solution for operational and bodywork repairs, allowing for reduced costs compared to new components while maintaining original geometry and body compatibility.
