We are aware that some of our customers are experiencing an issue with their vehicle’s central communication unit, known as the Porsche Communication Management (PCM), causing it to continuously reboot.
If your vehicle is equipped with PCM and you are experiencing this condition, performing a hard reset of the PCM should resolve the concern. To perform this reset please follow these steps:
***Before performing this procedure, ensure that your vehicle is located outdoors. Please note that hard resetting the PCM will remove all personalized settings
Press and hold the INFO button for approximately 10 seconds until the PCM reboots.
Press the CAR button.
Press the OPTION button or touch the tab of the same name in the header.
Select "SET PCM system">>"Reset PCM".
Select "Vehicle handover" This resets all settings to predefined values and deletes your personal settings and data (including addresses, destinations, radio stations, phone numbers, as well as the recordings in the Sport display).
Confirm the relevant prompt by selecting "Yes".
If after performing this procedure your vehicle continues to experience consistent reboots please contact your local authorized dealership to schedule an appointment for further diagnosis.
