Hello, this problem has been happening recently in my '87 260E. The doors will lock at the moment i'm there, and sometime when I get back, sometimes an hour or sometimes all day, the doors unlock themselves. I'm not totally defensless, as the alarm is still active ( I tried to open) but this is a problem. Anyone have any ideas? Nothing major has happened and it hasn't been in for a tune up recently....
Thanks
-Nathan

Join the club mate.

Mines haven't started unlocking but they are locking on their own.

For the unlock problem you likely have a leak in the vacuum system for the locks. As to the locking on it's own??? You may want to do a search on this forum as just about everyone eventually has a locking issue on this body.

It's not a hydraulic system, it's electrical and vacuum. Each door has a door lock actuator, and they sometimes fail. But the service CD has a very detailed diagnostic routine for the door lock system. Getting the CD and following the diagnostic routine would be my next step.
