After confirming the correct pressure, inspect each tire for visible damage, such as punctures, cuts, or bulges, and look for any debris lodged in the treads that could lead to a leak. If the tire pressure is adequate and the tires appear intact, proceed to reset the tire pressure monitoring system (TPMS), as it may need recalibration after adjustments. Refer to your vehicle's manual for specific reset instructions. If the warning light persists despite these checks, it may signal a more complex issue, such as a faulty sensor or a malfunction within the TPMS. In this case, consulting a qualified mechanic or an authorized Audi service center is recommended for a thorough diagnosis and repair. By systematically addressing these steps, you can effectively troubleshoot the tire pressure warning light and maintain your vehicle's safety and performance.
