The support structure of the flap has been designed to work with the original body mount and the factory opening mechanism.

Original Mercedes branding ensures the maintenance of proper rigidity, the correct opening angle, and proper alignment with the fender line.

The component belongs to a group of parts responsible for protecting the fuel system, which is why its proper operation is important for both user comfort and the long-term operation of the vehicle.

• factory fit to the body without geometry issues,

For many Mercedes W164 users, using an original fuel filler flap is the best way to restore full functionality after mechanical damage, vandalism, or corrosion of the original part.

Practical installation and maintenance tips

Before installation, it is worth verifying the compatibility of the part with the vehicle based on the manufacturer's markings or catalog data to ensure full compatibility with the specific body version. During installation, it is recommended to:

• check the condition of the hinge and mounting points on the body,
• check the operation of the opening and closing mechanism after installation,
