If the tire pressure is correct and the tires appear undamaged, the next step is to reset the tire pressure monitoring system (TPMS), as sometimes the system may require a reset to clear any false warnings. Refer to your Audi A5's manual for specific instructions on how to perform this reset. If the warning light remains illuminated after these steps, it may indicate a more complex issue that requires professional attention, so consider visiting a mechanic or an Audi dealership for a comprehensive diagnosis and repair.

Additionally, the tire pressure monitoring system may need recalibration, a process that can often be performed by following the vehicle's manual instructions. Electrical issues, such as damaged wiring or a blown fuse, can also trigger the warning light, necessitating a careful inspection of the vehicle's electrical components. Lastly, if all else fails, the tire pressure monitoring system itself may be malfunctioning, which could require diagnostic testing to identify the root cause.
