Thought I would share a problem I had with the alarm falsely activating on a s204, only way to stop it activating was to go through the ritual of pushing the interior button for deactivating the interior ultrasonic sensors which stopped the problem and every time I forgot the alarm would sound and then after a few months it stopped going off, so I thought happy days but one day I popped the bonnet to top up the fluids and then shut it and a few minutes after locking the car the alarm started to sound again.
Really fed up I thought perhaps there is a electric switch on the bonnet catch and after some investigating found it, removed it and found no actual fault with the micro switch but readjusted the the flap of metal that pushes against the micro switch so there's slightly more pressure pushing it down and after reassembling have had no more false alarms.
I am presuming that the bonnet switch is deactivated by the button in the cabin that deactivates the interior motion sensors, just a thought for anyone that has the same problem.
