Purpose and function of the component

The fuel filler flap on the Mercedes Vito W639 is responsible for protecting the fuel filler from dirt, moisture, and mechanical damage, while also contributing to the aesthetics of the side body panel. The offered component is structurally compatible with the manufacturer's factory solution, ensuring it maintains the correct geometry, body lines, and operation of the hinge and latch mechanism within the flap area.

Color and paint matching

The Obsidian Black Metallic - 197 finish is a characteristic metallic black shade used in Mercedes models. Using a component with the same paint code allows you to reduce or completely eliminate the need for repainting, which shortens repair time and reduces costs. For users who care about a consistent vehicle appearance, this is both aesthetically and practically significant – once installed, the flap does not differ in shape or finish type from the rest of the body panels.

Product characteristics and installation

The offered fuel filler flap is an original Mercedes brand component, which translates into maintaining factory dimensional tolerances and compatibility with standard mounts in the Vito W639 model. This facilitates installation in place of a damaged or corroded flap without the need for bodywork modifications or fitting aftermarket replacements. The product comes from the used body parts segment, which is a beneficial solution for economical vehicle repair while maintaining the manufacturer's original specifications.

The component is particularly useful in situations such as:

• replacing a damaged flap after a collision or side body scrape,
• repairing localized corrosion spots in the fuel filler area,
• restoring a consistent vehicle appearance after partial repainting.

Benefits of using an original fuel filler flap

Using an original fuel filler flap in Obsidian Black Metallic offers several significant advantages:

• Factory fitment – maintaining the correct body line and proper operation of the opening mechanism.
• Color consistency – compliance with the body paint code reduces the need for additional paint work.
• Time and cost savings – installing a ready-to-use, painted component shortens the repair process.
• Aesthetic finish of the fuel filler zone – visual improvement of the vehicle's side panel after damage or wear and tear.
