Purpose and Technical Function

The element is responsible for protecting the fuel filler neck from external contaminants and for maintaining the consistent geometry of the side panel. The construction is prepared for installation in the factory location, preserving the original mounting points and the characteristic BMW crease lines.

Color and Visual Match

The flap is finished in Mineral Grey Metallic – B39 paint, allowing for a uniform body appearance on cars in the same shade. The metallic paint finish provides the characteristic BMW color depth and harmonizes well with the styling of the X1 F48. In case of accident repairs or spot bodywork restoration, using a part with the same paint code minimizes the need for extensive painting of adjacent panels.

Characteristics of an Original BMW Part

The fuel filler flap is a part from the BMW OE line, which means it adheres to factory standards of quality and compatibility. The original geometry ensures:

• correct fit with the bodywork without the need for modifications,
• compatibility with the factory opening and closing mechanism,
• maintenance of the proper gap between the flap and adjacent body elements.

This allows the part to be used for both body and paint repairs, as well as for replacing a damaged flap after minor collisions or acts of vandalism.

Part Condition and Practical Application

The flap is offered as a used original part, enabling an economical repair while maintaining factory BMW specifications. This type of part is particularly suitable for situations where originality and minimizing paintwork are priorities. In many cases, installing a used flap in the same color can shorten repair time and reduce body preparation costs.
