Had this problem on my '98 SLK230. Check the PSE unit in the trunk, passenger side, towards front, behind CD-player. Fairly easy to get to ... just pull the trunk bottom panel out so you can see the spare tire, then it's a few clips I think to get the panel off. You'll see yellow foam insulation around the PSE. Chances are, water has leaked in via the hose, and is INSIDE the PSE module. Wiggle it around to see if water comes out of the corner ... if a lot of water has come out and you've had this problem for a while, like I did, many of the parts in the PSE are rusted and you'll have to replace it ... about 500 to 600 bucks I think for a new one. Good news is, you can disconnect all of the hoses, and the alarm issue will go away. Bad news is, you will lose central locking (including gas access, so you'll have to get that sorted out), alarm, and I think one other thing but non-essential to driving the vehicle.

If you don't know how to, have a dealer or indie and set the gas access door to permanent unlock until you can get a new PSE.
