my Volkswagen Passat B8 (2015-2022) fuel gauge is stuck how to fix it

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the battery to avoid electrical shorts.
• Ensure the vehicle is on a flat surface and the engine is off.

2. Access the Fuel Sender Unit

• Remove the rear seat or access panel to reach the fuel pump module (if applicable).
• Use a socket set to remove the mounting bolts of the fuel pump module.
• Carefully lift the module from the tank, avoiding damage to the fuel lines.

3. Inspect and Test the Fuel Sender Unit

• Disconnect the electrical connector from the fuel sender unit.
• Use a multimeter to check the resistance of the fuel level sender. Compare the readings with the specifications in the service manual.
• If the resistance is outside the normal range, replace the sender unit.
• Inspect the float mechanism for any cracks or stuck positions.

4. Replace the Fuel Sender Unit (if necessary)

• If defective, remove the old fuel sender unit by disconnecting the retaining ring or clips.
• Install the new fuel sender unit by reversing the removal process, ensuring a tight fit without over-torquing the retaining ring.
• Reconnect the electrical connector securely.

5. Reassemble and Test

• Reinstall the fuel pump module and secure it with the previously removed bolts.
• Reattach the rear seat or access panel.
• Reconnect the battery and start the vehicle.
• Monitor the fuel gauge to ensure it operates correctly.
