Purpose and function in the vehicle

The offered fuel filler flap is a body component mounted in the rear part of the car, responsible for covering the fuel filler neck and sealing this area against dirt and moisture. A properly selected flap ensures:

• correct closing of the fuel filler area,
• protection against dust, water, and road salt,
• maintenance of the factory body lines in the area of the rear fender.

By using an original component, you maintain compliance with the factory body geometry, which facilitates installation and reduces the risk of leaks or improper fitment.

Calcite White – 650 color and visual fit

The cover is finished in the factory Calcite White – 650 color, widely used in Mercedes models. Using the original shade allows for:

• consistent connection with the existing paint without the need for full painting of the element,
• maintaining a uniform appearance of the rear body section,
• reducing the costs and time required for paint work.

For users who care about the aesthetics of the vehicle, this is a particularly beneficial solution, as replacing a damaged flap does not disrupt the visual continuity of the paint surface.

Construction, installation, and compatibility

The fuel filler flap belongs to the Fuel filler flaps and accessories group, which means it has been designed to work correctly with the factory hinge and lock mechanism in a given body model. The original Mercedes origin promotes:

• precise fitment with the body in the rear of the vehicle,
• maintaining the correct geometry of gaps between body panels,
• stable operation of the flap opening and closing mechanism.

The element comes from dismantling, which in practice means it is a used part, but one that retains its factory construction and purpose. With proper installation, it is possible to quickly restore full functionality to the fuel filler area.

Benefits of using an original fuel filler flap

Using an original fuel filler flap in Calcite White brings a number of practical benefits:

• Factory fit – maintaining original body lines and proper fitment with the rear fender.
• Color consistency – no need to experiment with paint shades, which reduces the risk of tone differences.
• Time savings during repair – replacing the element is usually faster than a full renovation of a damaged flap.
• Reasonable economic choice – a used part allows you to reduce repair costs while maintaining the manufacturer's original specification.

For body and paint shops as well as individual users, this is a practical solution for post-accident repairs or spot renovation of the rear body section.
