My Citroen Xantia alarm has started to go off at will.The siren sounds,the headlights light(but not flash!) and they stay illuminated even with the fuses removed! I have tried removing the alarm fuse....but to no avail.I`m wondering if it would helpto disconnect the alarm module and if so....where is it?

the alarm module on the xantia is located under the passenger wing the wheel arch liner will have to be removed to gain access then check the wiring harness and plug, corrosion and bad connections can cause false alarms
