Subject: Strange locking/unlocking behavior on my 9-5

99 9-5 SE, Manual Transmission, 2.3T I've had this problem for a while, started after I told the Saab guys to program the locking system to automatically lock all of the doors when I start driving and to have the remote unlock all when I push the button (instead of two button pushes for all) Anyway, the first time I saw this when: 1: open the trunk (either with remote or with the button on the door) 2: drive the car to the point where the doors would lock automatically 3: stop, close the trunk Now, start driving and when the doors lock, the trunk unlocks and opens. Stop, close the trunk, drive and it does the same thing. The only way to "clear" this was to close the trunk, open the trunk using. I've since found a number of cases where this happens, for example 1: get out of the car, open the trunk 2: lock the doors with the remote 3: close the trunk 4: open the doors to get in drive away and the trunk opens. Same way to clear, etc. The dealer told me that this must be a malfunctioning (I forget the name) but computer system that controls the central locking system and that it shoudl be replaced. I can live with this for the price that they quoted me. But this smells of a firmware BUG that could probably impact lots of others. I can't see how some kind of computer failure would only impact this tiny little area, something else would have to be going wrong. Anyway, anyone else who has the same setup as me (ie: doors lock when car moving, all doors open from remote on a single button) ever seen this one?
