• stable holding of the flap in the closed position while driving.

By using an original actuator, compatibility with the factory BMW installation is maintained, without the need for wiring or mounting modifications.

• factory fit for the mounting socket in the E85/E86 body,
• proper cooperation with the central locking system and comfort controllers,
• appropriate piston force, matched to the fuel flap's design.

By choosing this part, you gain consistency with other fuel system components and minimize the risk of issues with the flap not closing properly or central locking malfunctions.
