Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the vehicle battery to avoid any electrical issues during the repair.

2. Inspect and Clean

Remove any dirt or debris around the fuel flap area using a soft cloth.
Inspect the hinge for any visible signs of wear or damage.
If the hinge is obstructed, gently clean it to ensure free movement.

3. Check Manual Release Mechanism

Remove the cover panel where the manual release lever is located.
Inspect the lever for any broken components or disconnections.
If necessary, reconnect or replace the lever assembly.

4. Test Electronic Release Mechanism

Reconnect the battery and turn the ignition to the "On" position without starting the engine.
Use a multimeter to check for voltage at the fuel flap release solenoid.
If there is no voltage, troubleshoot the wiring and connectors leading to the solenoid.

5. Replace Components if Necessary

If the solenoid is faulty, remove it by unscrewing it from its mount.
Install the new solenoid by securing it in place and reconnecting the electrical connector.
Reassemble any covers or panels that were removed during the process.
