Changing Wheels and Tires, with Tire Pressure Monitoring System

Changing Wheels and Tires, with Tire Pressure Monitoring System

If wheels are changed (for example change from summer to winter tires), the tire pressure sensors data as soon as speed of new wheels exceeds 25 km/h. The new tire pressure sensor identification numbers are automatically recognized and read by control module.

An acceleration data check also occurs with vehicle speed. This process takes about 7 minutes.

The tire pressure monitoring control module (J502) must be in learning mode first before it can learn the tire pressure sensor automatically.

Vehicle must stand for 20 minutes for this. This takes 5 minutes after a recognized tire puncture.

If the standing time is observed and if the control module is not in the learning mode, the system will recognize a malfunction. The system only adapts the tire pressure monitoring sensors automatically after a 20 minute waiting period.

• When changing wheels, ensure only Volkswagen approved wheel/tires combinations with tire pressure given on fuel filler flap are installed.

• If unapproved wheel/tire combinations are installed, these must have a TUV certificate for the particular vehicle and a second wheel set must be programmed using the Vehicle Diagnostic Tester.

• Learning is also needed if tire pressure deviates from pressures given on fuel filler flap.

Wheel Sets with Other Specified Tire Pressures

If a vehicle is equipped with tires which have specified pressures different from those listed on fuel filler flap, these tires (2nd wheel set) can also be monitored by the Tire Pressure Monitoring System (TPMS).

Specified values for a second wheel set must be entered into the system using the Vehicle Diagnostic Tester.

The tire pressure sensors on wheels from 2nd set are not automatically recognized and learned by the Tire Pressure Monitoring System (as tire pressure sensor on Volkswagen approved wheel/tire combination set are).

To change to a 2nd wheel set, the following steps must be carried out:

• Read the identification numbers (IDs) on the tire pressure sensors before installing.

• Switch the TPMS to wheel set 2.

• Enter needed specified tire pressures and tire pressure sensor IDs in system.
