Technical specifications and purpose

The presented fuel filler flap is a component from the Fuel filler flaps and accessories category, designed specifically for the BMW 3 Series F31 estate body style. Its placement in the rear of the vehicle means it is responsible for both protecting the fuel filler neck and maintaining the continuity of the body's side profile. The construction, based on the original BMW design, guarantees proper fitment with the wheel arch, hinge, and opening mechanism.

Color and paint matching

The factory Mediterran Blue Metallic C10 color allows for a uniform paint tone without the need for additional painting, provided the color code is correctly matched. The metallic coating provides the characteristic depth and light reflections typical of original BMW paints, which is important for both aesthetic reasons and during potential bodywork repairs. For the best visual effect, it is recommended to compare the shade with adjacent body panels before installation.

Condition and service application

The fuel filler flap is offered as a used part, making it a cost-effective solution for accident repairs, bodywork corrections, or restoring the car to factory condition after localized damage. Its original origin promotes the maintenance of proper geometry, as well as compatibility with factory mounts and the opening mechanism in the BMW F31. It is a practical choice for body shops and individual users who want to reduce repair costs while maintaining appropriate quality.

Installation and maintenance tips

Before installation, it is recommended to:

• verify the vehicle model compatibility and mounting side,
• check the condition of the hinge and opening mechanism on the body,
• inspect the gaps and contact lines with the fender after initial fitting.

Regular cleaning of the fuel filler area and the flap seal reduces the risk of dirt and moisture accumulation, which translates into longer, trouble-free operation of the component and an aesthetic appearance of the rear body section.
