Diagnosing ABS Light on Audi Q5 (2018-2024)

Tools Required:

• OBD-II scanner with ABS compatibility.
• Digital multimeter.
• Jack and jack stands or a lift.
• Basic hand tools (sockets, wrenches, screwdrivers).

Repair Instructions:

1. Replacing a Faulty Wheel Speed Sensor:

   • Remove the sensor from its mounting location.
   • Disconnect the electrical connector.
   • Install the new sensor and connect the wiring.
   • Reinstall the wheel and torque lug nuts to manufacturer specifications.

2. Cleaning or Replacing Sensor Rings:

   • If the sensor ring is dirty, clean it with brake cleaner and a wire brush.
   • Replace if significantly damaged or corroded.

3. Repairing Wiring:

   • If damaged wiring is found, repair or replace the section using solder and heat-shrink tubing to protect the connection.

4. Clearing DTCs:

   • After completing repairs, use the OBD-II scanner to clear any stored DTCs.
   • Turn the ignition off, then back on, and verify if the ABS light remains off during a test drive.

Final Steps:

• Test drive the vehicle to ensure the ABS light does not illuminate and that ABS functionality is restored.
• Recheck for any stored or pending DTCs.
• If the light persists after repairs, further diagnosis may be required, potentially involving an ABS module replacement or professional evaluation.
