Characteristics and purpose of the component

The offered fuel filler flap is dedicated to the Mercedes S-Class W221 generation model and is mounted on the rear part of the body. The component belongs to the Fuel filler flaps and accessories group, which means it has been designed to ensure proper closing of the filler recess, protection of the fuel filler neck, and maintenance of the factory body line. The design is consistent with the solutions used by the manufacturer, allowing the flap to work seamlessly with the original hinge and lock mechanism.

Cavansite Blue Metallic color – visual matching

The factory paint in the Cavansite Blue Metallic - 890 shade allows for an aesthetic integration of the component into the rear bodywork without the need for additional painting (provided the vehicle has the same color code). This is particularly beneficial for post-accident repairs or spot body restoration, where color and paint structure consistency is crucial. The original color also facilitates the work of painters and body technicians by limiting the scope of surface preparation.

Condition, origin, and benefits of using a used part

The fuel filler flap is a used component sourced from a dismantled Mercedes vehicle. Using an original part from the secondary market allows you to maintain factory fitment and proper stiffness of the flap, which is important for both the tightness of the filler recess and the comfort of daily use. Compared to aftermarket replacements, an OEM component usually works better with existing hinges, springs, and the opening mechanism.

Why choose this fuel filler flap

Using an original fuel filler flap in Cavansite Blue Metallic - 890 is a solution that:

• restores the aesthetics of the rear bodywork after mechanical damage or corrosion,
• ensures compatibility with the factory opening and closing mechanism,
• reduces the need for additional painting work when the color code matches,
• supports the maintenance of the vehicle's value through the use of original components.
