Tools Required

  • OBD-II Scanner
  • Fuel Pressure Gauge
  • Socket Set
  • Screwdrivers
  • Line Wrench Set
  • Safety Glasses and Gloves

Repair Instructions: Replacing the Fuel Filter

Safety Precautions

  • Ensure the vehicle is on a flat surface.
  • Turn off the engine and allow it to cool.
  • Disconnect the battery to prevent accidental ignition.
  • Relieve fuel system pressure. Locate the fuel pump relay in the fuse box, start the engine, and remove the relay to stall the engine. This relieves the system pressure.

Step-by-Step Replacement

  1. Access the Fuel Filter:

    • The fuel filter in the Audi Q5 FY is typically located under the vehicle near the fuel tank.
    • Lift the vehicle using a jack and secure it on jack stands.
  2. Remove the Old Fuel Filter:

    • Locate the fuel filter and identify the fuel lines connected to it.
    • Place a clean container beneath the filter to catch any spilled fuel.
    • Use the line wrench to carefully loosen and disconnect the inlet and outlet fuel lines from the filter.
    • Remove any clamps or bolts securing the filter using a socket set.
    • Carefully remove the filter from its bracket.
  3. Install the New Fuel Filter:

    • Position the new fuel filter in the bracket. Ensure the flow direction indicated on the filter matches the flow direction of the fuel system.
    • Reattach the inlet and outlet fuel lines securely using the line wrench. Ensure there are no leaks.
    • Tighten any clamps or bolts to secure the filter in place.
  4. Re-pressurize the Fuel System:

    • Reinstall the fuel pump relay.
    • Reconnect the battery.
    • Turn the ignition to the "ON" position for a few seconds to allow the fuel pump to prime the system (do not start the engine yet).
    • Check for any leaks around the new filter.
  5. Test the Vehicle:

    • Start the engine and let it idle to ensure it runs smoothly.
    • Take the vehicle for a short test drive to verify the repair.
  6. Final Inspection:

    • After the test drive, perform a final inspection for leaks and proper operation.

Notes

  • Always use OEM or high-quality replacement filters to ensure longevity and proper fuel system function.
  • Dispose of the old fuel filter and any spilled fuel according to local environmental regulations.
