Purpose and function of the component

The presented fuel filler flap is dedicated to the rear body section of the Mercedes B-Class W245 generation. It is responsible for covering the fuel filler neck, protecting it from contaminants, and providing an aesthetic finish to the side surface of the vehicle. Thanks to its factory origin, the correct body lines are maintained, and the mounting gaps remain consistent with the manufacturer's design.

The component has been designed for proper fitment with the bodywork, which facilitates installation and reduces the need for additional bodywork adjustments. It is a practical solution for post-accident repairs, paint corrections, or replacing a damaged flap with an original part.

Color and paint matching

The flap is finished in the Kometgrau Comet Grey Metallic - 748 shade, used as a factory standard in selected Mercedes W245 models. Using the correct paint code allows for:

• maintaining a uniform color tone across the entire side of the vehicle,
• reducing the scope of potential paint touch-ups,
• aesthetically closing the fuel filler area after body repairs.

For the best visual effect, it is recommended to compare the shade with the vehicle's bodywork and – if necessary – perform polishing or a delicate paint correction by a professional painter.

Installation characteristics

The fuel filler flap is intended for installation in the rear part of the body, at the location of the factory fuel filler. The design of the component allows for the use of original mounting points and compatibility with the standard opening and closing mechanism, provided that the other components of the system are functional.

Before installation, it is worth verifying the compatibility of the component with the specific vehicle equipment version as well as the condition of the hinge and opening mechanism in the car. A correctly installed flap should open and close smoothly, without rubbing against adjacent body elements.

Condition and use in repairs

The offered component is in used condition, which makes it a practical choice for maintenance and post-accident repairs when the priority is to maintain the original geometry and body construction on a reasonable budget. This type of part works well as a factory replacement in situations where there has been:

• mechanical damage to the flap (cracks, dents),
• local corrosion around the fuel filler,
• a need to replace the element after body and paint repairs.

Technical support and component selection

When selecting a fuel filler flap for a specific Mercedes model, it is helpful to use the manufacturer's markings and vehicle data, such as model, generation, and body configuration. In case of doubt, it is worth consulting a mechanic or a painter to confirm the compatibility of the component with the car.
