Mercedes Fuel Filler Door Lock Actuator - VDO 406204021005V

Product Information

The fuel filler door lock actuator is an electronic or mechanical device that locks and unlocks the fuel filler door, preventing unauthorized access to the fuel cap and tank. Controlled by the vehicle’s central locking system or a dedicated switch, it ensures convenience, security, and proper sealing of the fuel system. Typically constructed with a compact motor, gears, and durable housing, the actuator is engineered for reliable operation under repeated use and exposure to varying temperatures.

• Fuel filler door does not lock or unlock – actuator no longer responds to central locking commands.
• Clicking noise or weak movement – caused by worn internal gears or a failing motor.
• Intermittent operation – due to electrical faults, poor connections, or internal wear.
