alarm

Hi all. My alarm on my ML270 CDi (53 plate) keeps going off for no reason. Have searched forum and think it may be the siren unit? Have seen them on Ebay for £100 but does the unit contain the battery for the siren and will solve the problem or are there other elements to replace? Many thanks...

How does one tell if these have been activated, is there an indicator light anywhere? I pressed the internal alarm button the other day, but it still went off with a dog inside!? Without such this is woeful! :fail

Finally a dry day to change my faulty alarm siren. Tested by locking the car and opening a door with the metal key. indicators flashed but not a peep from the alarm. I also wonder if the faulty siren is the cause of my slight current drain? I'll know soon enough. Anyway, this has been...
