Tyre pressure monitoring systems detect pressure loss on one or more wheels and warn the driver accordingly.

The tyre pressure monitoring system uses sensors installed in the wheels to measure the pressure and temperature inside the tyre. The system then transmits this information to a receiver in the vehicle.

The measured tyre pressures are continuously compared with specification values, which are entered by the driver. The driver can check the tyre pressures and temperatures at any time, and receive a warning if differences arise between the set pressure and the measured pressure.

Sensors on all four wheels are necessary for the system to work correctly. If the vehicle is supplied with winter wheels, these will already have the required sensors; otherwise they must be ordered separately from your Audi dealer.
