my Volkswagen Golf MK7 (2015-2019) has a sloshing sound in the fuel tank, is this normal?

Solution

1. Preparation

• Gather tools and parts needed for inspection and repair.
• Ensure the vehicle is parked on a level surface and the engine is off.
• Disconnect the negative battery terminal to prevent electrical issues.

2. Inspect Fuel Tank

• Sub-steps:
  • Visually inspect the fuel tank for any signs of cracks, dents, or corrosion.
  • Look for any fuel leaks around the tank and its connections.
• Tools Required: Flashlight, mirror

3. Check Fuel Pump Functionality

• Sub-steps:
  • Reconnect the battery terminal and turn the ignition to the "ON" position without starting the engine.
  • Listen for the fuel pump priming sound for approximately 2-3 seconds.
  • If no sound is heard, further inspect the fuel pump fuse and relay.
• Tools Required: Multimeter, fuse puller

4. Address Fuel Level Concerns

• Sub-steps:
  • If the fuel level is low, fill the tank to the recommended level.
  • Monitor the fuel gauge for accuracy after refilling.

5. Reassemble and Test

• Sub-steps:
  • Reconnect any components that were disconnected during inspection.
