After a couple of trips to the dealer they fixed it under warranty.
They just needed to connect the PIWIS computer and reset all the devices.
It was kind of lame that the old service manager tried to tell me that my 3,000.00 extended factory warranty did not cover it until I pushed the issue with her manager.
I will definitely use a battery maintainer that typically comes with an emergency backup battery like this one. Its the cigarette lighter to cigarette lighter adapter.

Amazon also has them seperately for about 6 bucks.

 

I sat in my 08 997 turbo for about 30 min with seat belt off, engine running...went to put seat belt on and the car shut off with a psm error. Restarted with no errors/no issues.

 

Would you mind explaining how do you disengage it?
thank you
