Purpose and Function of the BMW F31 Fuel Filler Flap

BMW F31 Fuel Filler Flap White 7300931 belongs to the group of body elements responsible for protecting the fuel filler neck and maintaining the seal around the cap. A correctly chosen flap:

• protects the filler neck from water, salt, and road debris,
• stabilizes the visual side line of the body,
• reduces the risk of corrosion around the fuel filler neck,
• ensures proper cooperation with the opening and closing mechanism.

Original origin from the BMW brand means maintaining the correct geometry, ensuring the flap operates smoothly in the factory hinge and does not cause stress in the bodywork.

Alpinweiss 3 Color – Matching the Body Paint

The presented fuel filler flap is finished in Alpinweiss 3 - 300 color, factory-applied to many BMW F31 3 Series models. Choosing an element in the same shade of paint allows, in most cases, to avoid additional painting or limit it to minimal correction, which shortens repair time and reduces its cost.

A uniform flap color compared to the rest of the body:

• improves the visual continuity of the side surface,
• facilitates maintaining the aesthetic value of the vehicle,
• reduces the risk of visible shade differences after repair.

Characteristics of a Used Part

The offered fuel filler flap comes from disassembly, meaning it is a used part, retaining its factory construction and mounting parameters. This type of element is a good solution for accident repairs or spot bodywork corrections, where maintaining original geometry and compatibility with the factory opening mechanism is a priority.

Choosing a used fuel filler flap:

• allows to maintain high compliance with BMW factory standards,
• is cost-effective compared to new parts,
• reduces production waste, supporting the reuse of parts.

Selection by Numbers and Integration with the Fuel System

The element belongs to the Fuel Filler Flaps and Accessories group, which are components that cooperate with the fuel system in the external area. When selecting a flap, it is advisable to verify compatibility by manufacturer numbers and by model and body version to ensure correct fit with the bodywork and lock mechanism.

For users who want to better understand the role of the fuel filler area in the entire fuel supply system, a guide describing the diagnostics and operation of the fuel system – injectors, pumps, and tank – will be useful. Detailed discussion can be found in the article Fuel System – Injectors, Pumps, and Fuel Tank: Maintenance and Repair.
