Purpose and function of the component

The fuel filler flap in the Mercedes S-Class W221 generation is responsible for covering the fuel tank inlet at the rear of the body, protecting the cap and the surrounding area from dirt and external factors. A properly selected flap ensures a correct fit with the fender line, which translates into maintaining factory geometry and panel gaps.

The original component from this series is designed for compatibility with the factory flap opening and closing mechanism, ensuring that standard fuel filler operation and proper lock and spring functionality are maintained after installation.

Cavansite Blue Metallic color – visual matching

The factory Cavansite Blue Metallic - 890 paint is a distinctive, dark shade of blue with a metallic effect, used in many Mercedes S-Class W221 units. Using a flap in the same color allows you to reduce or completely eliminate the need for additional painting, provided that the other body elements are in good visual condition.

For body shops and users who care about a consistent look of the car, this is a practical solution that facilitates restoring the vehicle's aesthetics after a collision, scratch, or corrosion in the fuel filler area.

Installation and operational characteristics

The fuel filler flap designed for the rear body section is structurally matched to the factory mounting in the Mercedes W221. This means it can be installed in place of a damaged flap without the need for body modifications or interference with the fender structure. In practice, this translates into shorter repair time and a lower risk of fitment issues.

As a body component from the Fuel filler flaps and accessories group, the product works with the existing fuel filler system without affecting the refueling process or the functionality of the cap. Proper fitment of the flap also helps limit the ingress of water and dirt into the filler area, which promotes longer, trouble-free operation.

Used condition – practical benefits

A used, original body component is a solution often chosen by conscious users and workshops that want to combine reasonable repair costs with the preservation of factory build quality. In the case of the fuel filler flap, this means access to a part with a design that meets the manufacturer's requirements, while reducing expenses compared to a new component.
