Mercedes Fuel Filler Door Lock Actuator - Genuine Mercedes 000820770380

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.

You may not realize this, but the parts that make up your Mercedes-Benz are not necessarily manufactured by Mercedes-Benz.

In fact, many of these manufacturers have been making parts for Mercedes-Benz for decades. In our industry these manufacturers are called OEM (Original Equipment Manufacturers), and these are often brands you recognize, including Lemforder, ZF, Sachs, Bosch, Valeo, Zimmermann, Siemens VDO, Corteco, and more. Don’t be surprised to open that Genuine Mercedes-Benz parts box and find an OEM branded part inside, simply with the addition of a Mercedes-Benz logo.
