Tire Pressure Sensor: Notes
IMPORTANT:
1st generation TPM wheel electronics (2005-07) are not compatible with 2nd generation TPM wheel electronics (as of 2008). If wheels with 1st generation TPM wheel electronics are fitted on a vehicle with 2nd generation TPM wheel electronics (or vice versa), the TPM system will not recognise the wheel electronics. The TPM system is not active and a corresponding warning message appears in the instrument cluster. In addition, the wheel electronics are reported as defective in the fault memory of the TPM control unit. All handling procedures are the same.
NOTE:
Use only plastic valve caps. Use original Porsche metal valves.
