Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, basic hand tools (screwdriver set, socket set).
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Accessing the Fuel Level Sensor

Raise the vehicle using a jack and secure it with jack stands.
Remove the rear seat or access panel to reach the fuel tank’s access cover.
Unscrew and remove the access cover to expose the fuel pump assembly.

3. Inspect and Replace the Fuel Level Sensor

Disconnect the electrical connector from the fuel level sensor.
Remove the fuel pump assembly by unscrewing the retaining ring and lifting the assembly out of the tank.
Inspect the fuel level sensor for damage; if faulty, replace it with a new sensor.
- Note: Ensure the replacement sensor is compatible with the BMW X5 G05 model.
Reinstall the fuel pump assembly, ensuring the O-ring is in place to prevent leaks.

4. Reassembly and Testing

Reconnect the electrical connector to the fuel level sensor.
Replace the access cover and secure it with screws.
Reinstall the rear seat or access panel.
Reconnect the vehicle battery and start the engine to check the fuel gauge operation.
