'Comfort Opening' and 'Comfort Closing' are finctions that can be coded with a Porsche PIWIS tester.
On early 987s there was an issue with people arriving back at their parked cars to find the windows and/or luggage compartment open, but the car locked. This was due to unintentional unlocking by the remote button being activated in a trouser pocket or handbag. The response time was set too low at the factory, and the car would unlock (or open the front compartment) with a very quick press of the button. If the unlock button was held for a little longer, the windows would open too. After a minute, the car would re-lock automatically (if a door wasn't opened), leaving the windows/compartment open. There was a bulletin to extend the time for the buttons to respond, but a lot of cars didn't get done.
Bear that in mind if you have it coded - make sure the time has been extended. PPersonally, I set mine to comfort close only, so it could never be an issue.
