Porsche PCM Update
Porsche Communication Management (PCM) Update & Reset
Sirius XM Radio recently sent out a refresh signal that caused major functional issues with the PCM (Center Touchscreen). Unfortunately, this update appears to be affecting virtually all modern Porsche vehicles. If your Porsche PCM has started malfunctioning the Sirius XM update is likely the issue.
At this time, Porsche has not released an official service bulletin or fix for these issues. However, rebooting the system should put everything back to normal. Keep in mind that this reboot will also reset all your personal settings. If you have any questions or need help getting the PCM in your Porsche fixed, give us a call or swing by our service center.
