If the tire pressure is within the acceptable range, proceed to inspect the tires for any visible damage, such as punctures, cuts, or bulges, which could indicate a leak. Next, examine the valve stems for any signs of wear or leaks, as faulty valve stems can also contribute to pressure loss. If everything appears normal, consider resetting the Tire Pressure Monitoring System (TPMS) according to the instructions in your owner's manual, as this can sometimes resolve false warnings. However, if the warning light persists after these steps, it may be time to consult a professional mechanic or an Audi dealership for a comprehensive diagnosis, as there could be underlying issues with the TPMS or the tires themselves.
