The alarm on my MY00 (sigma M30) keeps going off after I lock the car its seems to happen about a minute or two after arming, does anyone know of a way to adjust the sensitivity

mine does this aswell!

Does it happen mainly when it is windy? Does it help if you close the vent slider so that air is only circulated in the car?
I'm still testing to see if this helps mine but it seems to!

Adrian.

I had the same alarm fitted to a jeep cherokee and found especialy when cold the alarm would set itself off, as mentioned by adrian i found that closing the air vents cured this problem.

Yes it seems to happen when cold after short journeys, I will try the vent idea.
