Alarm sounding when temperature drops

[audandjohn]

My crossfire doesn't like being left out in the cold. If it is not garaged, and the temperature drops below zero the alarm goes off. Does anyone else have this problem or have any idea how I can fix it? I've no idea what it will be like if I get snow on the roof but I think I will be finding out soon!! Love to hear any suggestions. Audrey

Hi and welcome to the forum. I would guess it's a problem related to your car battery, as when the temperature drops the voltage can fall thus making the alarm module think a door has been opened. My XF stays out all year round and I woke to 4 inches of snow all over the other day and no complaints from neighbours of the alarm going off.

That does sound like a battery problem. But if it’s not the battery, it might be damp getting in behind the courtesy light in the roof. I know that sounds strange, but it happened to me. Damp gets into the printed circuit board above the courtesy light which is something to do with the alarm. Second hand one fixed it.

Good luck
