Alarm and Locks Problem
For about 3 weeks now I have this problem where while I am driving the car and out of nowhere the locks either lock or unlock. I am not sure if this is related but the alarm seems to go off at will. I cant leave the car for more than 3 hours without if going off it seems. If anyone has any idea or info on what the problem may be please post. I would appreciate it.

There is a PSE module in the trunk which contains both a pneumatic pump for the locks and electronics to control stuff including the alarm. This area seems prone to moisture. My alarm was not working and it was due to moisture-related damage. The PSE was replaced under warranty. I'd check there first.

Alarm problem
On our SLK230 the alarm would sound after we locked the doors. I took your suggestion to check the PSE module. I opened up the module (the bottom pops off very easily) and found corrosion on the printed circuit board. I cleaned off the corrosion, reassembled the unit, reinstalled it and now it works fine.
Thank you for pointing me in that direction.
