Purpose and function of the component

The offered fuel filler flap is a body part from the Rear wheel arches and fenders group, mounted in the rear zone of the vehicle, within the fuel filler area. It provides protection for the filler against dirt, moisture, and mechanical damage, while also ensuring a cohesive, sporty look for the side bodywork of the BMW 4 Series F82 M4.

The component comes from a BMW vehicle and is consistent with the factory body geometry, which translates into proper alignment with the fender line and other rear panels.

Color and visual fit

The flap is finished in Mineral Grau Metallic – B39, characteristic of many BMW 4 Series M4 configurations. The metallic paint ensures consistency with the manufacturer's original palette, which makes it easier to maintain a uniform paint surface along the entire side of the vehicle.

For owners of cars in the same shade, this means the possibility of replacing a damaged component without the need to change the color, and in many cases, also minimizing the scope of paintwork required.

Product characteristics and condition

The offered BMW fuel filler flap belongs to the group of used parts, which is important when planning a repair or body restoration budget. Such components are frequently chosen for post-accident repairs, localized bodywork corrections, and restoring the car to a condition close to factory specifications.

As an original BMW part, it retains the correct shape, mounting points, and characteristic embossments, which facilitates installation and reduces the risk of issues with the gap lines between the flap and the rear fender.

Application in body repairs

The fuel filler flap in the BMW F82 M4 is a component often replaced after minor collisions, parking scrapes, or mechanical damage in the area of the rear wheel arch. Using an original component allows for:

• restoring the proper operation of the fuel filler opening mechanism,
• achieving even gaps between the flap and the rear fender,
• maintaining a cohesive side body line,
• reducing the scope of body and paint work.
