Wheel Changing







Wheel Changing

If the wheels are changed (for example, changed from summer to winter tires), the wheel electronics send data as soon as the speed of the new wheels exceeds 25 km/h (15 mph). The wheel electronics identification numbers are automatically recognized and read by the control module.

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

The tire pressure monitoring control module must first be in the learning mode before it can automatically learn the wheel electronics.

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

If the standing time is not followed, the control module is not in the learning mode so the system recognizes a malfunction and can only automatically learn the wheel electronics after standing 20 minutes.

When changing wheels, be sure to install only Volkswagen approved wheel and tire combinations with tire pressures listed on the tank flap.

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 the tire pressure deviates from the 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.

Wheel electronics on wheels from a 2nd set are not automatically recognized and learned by the TPMS (as wheel electronics on Volkswagen approved wheel/tire combination set are).

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

Read the wheel electronic (tire pressure sensor) identification numbers (IDs) before installing.

Switch the TPMS to wheel set 2.

Enter the needed specified tire pressures and wheel electronic IDs in the system.
