Tire Pressure Monitoring With Pressure Sensor

WARNING: This page does not describe the selected car, but rather 18 other vehicles, including the 2016 Audi S4, 2016 Audi A4 Quattro, 2016 Audi A4, 2015 Audi S4, and 2015 Audi A4 Quattro. However, it is still accessible from the selected car via links, so may be relevant.

WARNING:

If tire sealant was used, then the wheel electronics on that particular wheel must be replaced.

The wheel electronics, that is, the system pressure sensor, forms a physical unit with the valve.

NOTE:

The lettering on the wheel electronics shows which system is installed.

NOTE:

Currently there are two versions of the wheel electronics.

Beru TPMS, refer to WHEEL ELECTRONICS, TPMS, BERU SYSTEM .

Siemens TPMS, refer to WHEEL ELECTRONICS, TPMS, SIEMENS SYSTEM .

Direct measuring systems according to model METAL VALVE BODY, REMOVING AND INSTALLING .

Indirect measuring systems according to model METAL VALVE BODY, REMOVING AND INSTALLING .

The pressure sensor transfers the recorded signals to the tire pressure monitoring system antenna.

The pressure sensor is connected firmly to the rim with a threaded connection.

If the tire pressure drops, the driver is warned via the pressure sensor in the instrument cluster.

To inform the driver, this system transfers the tire pressure values via a control module to the driver information system in the instrument cluster.

NOTE:

If vehicles with tire pressure monitoring sensors are transported in airplanes, the airline must be informed of the sensors.

The correct allocation must be observed, otherwise the tire pressure monitoring will not function correctly.

More detailed information on this system can be found in SSP 219 "Electronic tire pressure monitoring".
