My car has started unlocking itself. When I'm driving, it will unlock itself, usually within seconds of being locked. Sometimes it stays locked for a minute or two, then unlocks itself. If I push down on either the driver or passenger side door lock, the red light on the center console switch comes on and it will stay locked, but if I manually push down on both, it will unlock again. I can't lock it when it's parked because it will unlock itself and set off the alarm. If I lock it, parked, without setting the alarm (close driver door, open passenger door, reach in and lock at center console, then close passenger door), it will invariably be unlocked when I return to the car. Do I need an exorcist?

mine did just the opposite , it kept locking itself from time to time with no rhyme or reason triggering it  . and then just like that it stopped by itself after a week of those symptoms  .   gremlins.    i cant imagine it can be anything else but an imperfect contact point at / in the central locking switch ..

I had this problem, the actuator was mis-aligned, telling the computer someone had pulled the lock handle up, causing the system to open.  This of course all happened after I was doing some handle work, I just went and moved the actuator a little closer to the lock if I recall and it fixed the problem for me.  The central locking uses ranges it reads from the the actuator to determine if the lock is open or closed.

 

The factory service manuals, even if I did not have the correct code reading tools, helped me to glean a lot of insight on how the alarm and central locking work.

 

Easiest way, and I resisted for a bit, is to make an odb I porsche connector to a ODBII connector and use the durametric to pull the code.
