Cayenne S Displays Passenger Door Open

[DUstinZnCali]

Display and lights go on and off displaying that the passenger door is open while driving. (Door is of course closer). Recently purchased the vehicle hoping this was a minor issue. There is a problem opening doors where You have to push in and pull or pull the handles a few times on about all doors to get it to unlock /open the doors as well. Probably 2 issues but worth noting. Any suggestions would be most appreciated.

Same problem here but instead its my rear hatch, the boot door that displays as if wasn't closed but it is and a beep that goes off quiet often...hope somebody can help us!

In both cases you will likely need Durametric or PIWIS to diagnose and pinpoint the problem(s).

The modern electronics in these cars today run all accessory features through electronic controllers that can be easily tested for component failures.
