Tire Monitoring System: Service Precautions

General Repair Information

Observe notes about usage in your owners manual.

The tire pressure monitoring system monitors the pressure of the four tires while driving. Damaged tire pressure sensors should be replaced for safety reasons.

Do not clean tire pressure sensors with steam blasting or strong compressed air.

For safety reasons, the tire pressure monitoring sensor should be replaced and the rim cleaned after using tire sealant.

The tire pressure monitoring system consists of a control module, a central antenna integrated in the control module and one tire pressure sensor in each of the four wheels.

If wheel positions on the vehicle are changed, tires are changed, tire pressure sensors are replaced or pressures are changed, control module must be readapted.

Note:
^ When changing a tire with tire pressure monitoring sensors (summer/winter tires), tire pressure must be checked and the sensor readapted to the control module.

A fault may be saved in the DTC memory if:

There is a system malfunction.

When installing less than four wheels with tire pressure sensors.

When installing winter tires or incorrect tire pressure sensors. (If this is the case, the yellow warning lamp in instrument cluster "system malfunction diagram" is set and cannot be deactivated by the system.)

The system has detected new sensors but the tire pressure monitoring button E226 has not been pressed yet to confirm the current pressures. (In this case, the system malfunction is erased by pressing the button.)
