Technical characteristics and fitment

The offered fuel filler flap is an original component, designed specifically for the C-Class CL body (designation CL203), ensuring proper geometry, adequate rigidity, and correct operation with the hinge and opening mechanism. The flap construction is prepared for installation at factory mounting points, which facilitates service and reduces the need for additional bodywork modifications.

The Obsidian Black Metallic – 197 color is one of the popular paints used by Mercedes-Benz, which is why using this flap allows for maintaining a consistent stylistic line of the body, and in many cases, limits the scope of painting to a minimum (or allows for its precise matching).

Application in the fuel system and bodywork

The fuel filler flap serves a protective function for the filler neck and fuel tank cap, securing them against contaminants, moisture, and mechanical damage. A properly selected element from the Fuel filler flaps and accessories group contributes to:

• maintaining the tightness of the fuel filler area,
• protection against corrosion of elements around the filler socket,
• stable guidance of the flap during opening and closing,
• maintaining the factory body line and even gaps between panels.

In the case of work on the fuel system – replacing the cap, hoses, or tank – a properly selected fuel filler flap is an important addition to the repair, allowing for the completion of the entire service process from a visual perspective as well.

Benefits of using an original fuel filler flap

Using an original fuel filler flap in Obsidian Black Metallic brings a number of practical benefits:

• Precise fit with the bodywork – proper adhesion to the fender and maintaining even gaps between panels.
• Compatibility with the factory mechanism – correct cooperation with the hinge, spring, and potential central locking (if present in the vehicle's configuration).
• Color consistency – paint code 197 allows for aesthetic matching to the rest of the body, which is significant for post-accident and renovation repairs.
• Reduction of repair costs – the possibility of using an element in the current paint finish often shortens work time and reduces the scope of painting.

Condition and service purpose

The item comes from the secondary market, which makes it an attractive solution for maintenance repairs, corrections after minor collisions, or restoring the vehicle to full functionality after damage to the side part of the body. This type of component is particularly useful in situations where the priority is to maintain the original construction and body geometry while optimizing service costs.
