Brilliance V5 (1st generation): Fuel Filler Door Actuator Repair

The fuel filler door won't open or close because of a stuck actuator pin, a broken rod or cable, a worn plastic latch, or a faulty electric actuator. The exact removal procedure for the V5 is not documented in publicly available service materials, so the general diagnostic and repair procedure is given below. Check the mounting details on the vehicle.

Difficulty: Medium Time: 1-2 hours Steps: 8 Tools: screwdriver set, plastic trim removal tools, 8-10 mm sockets, multimeter, flashlight, silicone grease

Part

🔩 fuel filler door actuator (lock) assembly, or, on a cable-operated version, the release handle with cable. The part number for the V5 is not reliably confirmed, so look up the part by name

Step by step

8 steps

Determine the actuator type. Lock and unlock the car with the central locking and listen near the rear left corner. If you hear a click or a buzz, the actuator is electric. If the door opens only with a lever or a button by the seat, the actuator is cable-operated.
If the door is jammed, don't pry it open by force. Gently press on the edge of the door while operating the lever or central locking at the same time. In freezing weather, first warm the door with a hair dryer or warm water, because ice is often the cause.
Open the trunk and remove the side trim of the rear left fender near the filler neck. The trim is held by plastic clips and sometimes by a few screws. Pry the clips out with a trim tool so you don't break them.
Find the filler door actuator. It is a small unit with an extending pin or latch on the body next to the filler neck. Check the pin for sticking, and check the rod or cable for breaks and for slipping off its mount.
For an electric actuator, check the power supply. Disconnect the connector and apply 12 V from the battery to the actuator terminals; reversing the polarity reverses the direction of travel. If the pin moves, the actuator is good and the cause is in the wiring, a fuse, or the central locking module. If it doesn't move, the actuator needs to be replaced.
If the actuator works but sticks, clean the pin and its guide and lubricate them with silicone grease. Don't use thick lithium grease, because it stiffens in the cold.
To replace it, disconnect the connector or rod, release the actuator's retainer (usually by turning or sliding it in its slots), and remove it. Install the new actuator in the same position, plug in the connector, and secure the rod.
Before reassembling the trim, test opening and closing the fuel filler door several times. Make sure the pin enters the mating part of the door without binding. Then reinstall the trim.

Common mistakes and warnings

Work with the engine off, away from open flames, and keep fuel off the electrical connectors. Do not damage the filler neck or the fuel hoses when removing the trim. If the actuator's electrical system is fine but the door still doesn't work because of a deformed body panel or door, it's better to take the car to a body shop.
