TPMS Reminder Reset - Procedure 03
If wheels with wheel electronics from the 1st TPM generation are mounted on a vehicle with a 2nd generation TPM system (or vice versa), the wheel electronics will not be recognized by the TPM system. The TPM system is not active and a corresponding warning is displayed in the multi-function display of the instrument cluster. The wheel electronics will also be stored as defective in the fault memory of the TPM control unit.
Wheel electronics unit (sensor) part numbers are:
- 2005-07: 997.606.021.00 (433 MHz)
- 2008: 997.606.021.01 (433 MHz)
- 2009-: 997.606.021.20 (433 MHz)
Tire Pressure Monitoring begins to "learn" new tire pressure sensors after a wheel change or sensor replacement after updating the tire specification settings. During the Learn process, the TPMS recognizes the wheels and their locations. A "No Monitoring" message appears on the multi-purpose display. The wheel learning process takes place exclusively when the vehicle is being driven above 16 mph (25 km/h). Tire Pressure Monitoring requires a certain amount of time to learn the wheels.
Updating Tire Specification Settings:
- Push operating lever forward in order to switch on the selection field.
- Select "TPC" with the operating lever.
- Push operating lever forward. The display changes to the Tire pressure menu.
- Select "Set" with the operating lever.
- Push the operating lever forward. Select desired tire type: summer or winter.
- Push operating lever forward. A display for confirming the selected type of tire appears.
- Select "Continue" and push the operating lever forward.
- Select the appropriate tire size (18 or 19 inch) and push operating lever forwards. A display for confirming the selected tire size appears.
- If "Process complete" is displayed, learning mode will be initiated.
- Drive vehicle above 16 mph (25 km/h) until correct tire pressures are displayed.
