Vauxhall Vectra alarm keeps going off for no known reason.

Car: Vauxhall Vectra
Variant: 1.9 cdti 150 elite
Model Year: 2006
Categories: Electrics, ECU, Warnings & Lights
I don't want to disable the alarm, I just want to stop it activating for no reason. I can stop it but defeats the object of having an alarm. I just wonder if anyone has any idea of how to get it back to normal. Thank you in advance.

Bonnet sensor is common fault.

Possibly mass movement sensor

On some Vectra's you have the option of having the interior movement detection turned off .Check handbook .
