Recently got a lovely E220 CDi Estate... the annoying thing is that the alarm decides to go off weneva it wants! It can be 1 minute after locking or 1 hour.... disconnected the alarm today cos the neighbours are getting cheesed and so am i...after it resets it may go off or decide to wait a while...indicators go crazy...but at least its quiet
read the thread on the 95 merc sim probs... any ideas...? unsure what it could be etc...

Check the battery 1st. ifthe voltage is dropping quickly it will trigger the alarm at random.

yes i have done that and the garage tells me its all good and charged so could there still be a voltage drop...? i checked it a few minutes after driving to the garage...

I had exactly the same fault - a change in the atmospheric pressure causes the interior sensors to set the alarm off, seemingly randomly. Solution - cover the interior sensors (above the front seat seat belt anchor points) with black insulating tape. The alarm has never gone off since.
