Purpose and function of the component

The described fuel filler flap is designed specifically for the rear body area of the Audi A8 D4 generation. It is responsible for covering the fuel filler neck, protecting it from contaminants, and maintaining the continuity of the body lines. Thanks to its factory design, it ensures proper operation with the opening and closing mechanism of the fuel flap, which translates into convenient handling during refueling.

Color and paint matching

The component is finished in the original Quartz Grey Metallic – Y7G color, characteristic of selected Audi A8 D4 configurations. Using the correct paint code allows for visual consistency with the other body panels, which is particularly important for post-accident repairs or spot restoration. In many cases, this allows for installation without the need for repainting, provided that the other elements of the vehicle have maintained a similar coating condition.

Technical characteristics and installation

The fuel filler flap is a factory Audi component, prepared for installation in the rear part of the body. The design provides for the use of original mounting points and compatibility with the standard flap mechanism, which facilitates installation in workshop or service conditions. By maintaining dimensions consistent with the manufacturer's design, precise fitting with adjacent body elements is possible without the need for adjustments or modifications.

Condition of the component and service application

The product is a used original component, which in practice means maintaining factory geometry and compatibility with the Audi A8 D4 body while offering an attractive cost-to-quality ratio. This type of part is suitable for both post-accident repairs and replacing a flap damaged mechanically or through wear and tear, allowing for the restoration of the correct appearance and functionality of the fuel filler area.
