Purpose and technical function

The presented fuel filler flap has been designed for the W166 series body and Diesel fuel systems. It is responsible for covering the filler neck, protecting against contaminants, and providing stable guidance for the cap and associated elements, which is essential for the tightness and operational safety of the fuel system.

As a body component from the Fuel filler flaps and accessories group, the flap works with the factory hinge and lock mechanism, maintaining the fender line and correct assembly gaps. This allows for maintaining aesthetics and aerodynamics consistent with the manufacturer's design after replacement.

Color and visual fit

The flap is finished in the Palladium Silver Metallic - 792 shade, which allows for a consistent match to the bodywork in the same paint code without the need for additional painting or with minimal correction. The metallic coating provides the characteristic play of light for this color and blends well with the styling line of W166 models.

Selecting a flap in the correct color reduces the risk of shade differences between the replaced element and other body panels, which is particularly important for post-accident repairs and restoring the vehicle to a near-factory condition.

Performance parameters and advantages

The original design intended for Diesel fuel ensures compatibility with the standard filler neck and sealing elements. In practice, this means:

• proper closing and maintaining the flap in the rest position,
• stable guidance during opening and closing,
• protection of the filler area against water, mud, and fine contaminants.

The used component allows for an economical repair while maintaining factory geometry and mounts, which facilitates installation and reduces the need for additional bodywork modifications.

Brand and vehicle compatibility

The product comes from the Mercedes brand, which translates to compliance with factory quality and dimension standards. The flap is prepared to work with the original hinges and locking mechanism used in the W166 series, so installation comes down to proper seating in the factory location.

Additionally, the part has a dedicated OEM number and associated interchangeable numbers, which facilitates verification of compatibility with a specific version of body equipment and fuel system.

Condition and practical application

The flap is offered as used, which allows for cost-effective restoration of the full functionality of the fuel filler area while maintaining the original design. This solution is particularly useful for repairs after minor collisions, parking damage, or local corrosion.

The selection of the appropriate part can be further optimized by using markings such as SKU or parameters related to the fuel type Diesel and paint shade Palladium Silver Metallic - 792, which minimizes the risk of ordering errors.
