How to remove Alarm/siren 2003 CLK 320
Hello,
I had the problem of my alarm/siren sound when I was driving and just for no reason. I found some threads on here on how to remove it (which were helpful) but i found a simpler way and wanted to share the how to;
Tools
flat head screwdriver
pliers
socket wrench
5/16 socket
10mm socket
Procedures
-Locate the sound/siren speaker (most threads say behind front driver side tire, but mine was behind front passenger side tire)
-Turn wheels all the way left (this way you do not have to jack the car up or remove the tire)
-remove the splash guard from behind the front passenger tire (not completely, read on and see exactly what I'm talking about)
-remove 1, 5/16 screw from the bottom of panel
-remove 2, plastic screws/anchors bottom/side from panel
-remove 2, 10mm nuts from middle of panel
-wiggle and pry open the panel with something and the alarm/siren should be visible at this point.
-the bracket holding the siren in place has 3, 5/16 nuts to be removed (once this 3 nuts are removed the bracket and siren will be hanging)
-squeeze the wire clip from the siren and pull apart
-the siren and bracket should fall into your hand and your done.
Yes the car had no alarm at this point but I didn't want to buy another siren for $200-$400. The car shows no malfunction sign on dash and you can drive with no worries of the alarm sounding while your driving.

How about this?
Could you expose the siren wire, cut one side, splice in a pair of wires, run them up thru the passenger front door pillar into the glovebox, and install a toggle switch in the existing hole?
Just a thought.

I haven't tried that but, Yes in theory that should work. Then you use the toggle switch like a light switch turns on and off you light in a room, the toggle switch turns your siren power on/off. good thought davebut

w208 CLK320 2002
thank you very much for your help the same happened with my w208, when disconnecting the siren the alarm stopped flashing when closing, replaces the battery of the siren and now everything is ok. the siren on mine is near the left mile lighthouse. thank you very much, it helped a lot, because I was unaware that the siren has its own battery.

Location of Siren on my 2003 CLK320 Cabriolet
On my 2003 CLK320 Cabriolet (A208 Chassis) the alarm module is located just behind the driver's side fog light. There's a plastic access panel held on with 4 screws. Once the screws and the panel are removed, the alarm module is easily accessible. If the alarm is still OEM original, you may need a T-30 security screw adapter to remove the mounting screw. When installing the new unit an M10 nut replaces the annoying security screw. The job is a little easier if you raise the car about a foot using a jack and jackstand.
