Ensuring that all tires are inflated to the manufacturer’s recommended levels is crucial for both safety and performance. If the pressure is adequate, the issue may lie with a faulty tire pressure sensor, which could require recalibration or replacement. Additionally, some sensors are powered by batteries that can deplete over time, necessitating a sensor replacement if they are dead. Another possibility is a malfunction within the tire pressure monitoring system itself, which may need diagnostic testing to pinpoint the exact issue.

If you find any signs of damage, such as punctures or bulges, it is essential to have them inspected by a professional to prevent further complications. After addressing any pressure discrepancies or damage, resetting the tire pressure monitoring system (TPMS) is often necessary to clear the warning light. If the light persists, it may indicate a malfunction within the TPMS itself, necessitating a visit to a qualified mechanic or Audi dealership for a thorough diagnosis. By acting swiftly, you can maintain optimal tire performance and ensure a safer driving experience.
