To effectively diagnose a persistent tire pressure warning light on your 2025 Audi A6 Quattro, start by checking the tire pressure in all four tires, ensuring they are inflated to the manufacturer's recommended levels, as low pressure is a frequent culprit. Next, visually inspect each tire for any signs of damage, such as punctures or bulges, which could indicate air loss. If the tires appear to be in good condition, proceed to reset the tire pressure monitoring system following the instructions in your vehicle's manual; this can sometimes resolve the issue if it was triggered erroneously. Additionally, examine the valve stems for any signs of wear or leaks that might be affecting tire pressure. If the warning light persists, using a diagnostic tool to scan for fault codes related to the tire pressure monitoring system can help identify any underlying issues that may require professional attention. By following these steps, you can systematically troubleshoot the warning light and potentially resolve the issue without needing to visit a mechanic.
