What does the Audi TPMS light mean?

[Ferreira]

Audi TPMS stands for Tire Pressure Monitoring System, and the illuminated light indicates an issue with tire pressure. The reasons for the TPMS light turning on and the corresponding solutions are as follows: Reasons for the TPMS light turning on: The TPMS indicator may illuminate due to low tire pressure in one of the tires, insufficient sensor battery, a punctured tire (e.g., by a nail), or a malfunctioning tire pressure sensor. Solutions for the TPMS light turning on: When the TPMS light comes on, slow down and stop the vehicle to check which tire is causing the issue, avoiding sudden braking. If you have a portable inflation tool, you can measure the pressure of each tire and inflate them accordingly. If you don't have a portable inflation tool, drive slowly to the nearest repair shop for inflation.
