Alarm going off in the hot weather?

[M@tt_182]

I had this problem last year and today the dreaded alarm is back again! When the car is parked in direct sunlight the alarm goes off and then can't be re-armed again without a continous beep.

Today I disconnected the bonnet sensor and it's made no difference, what's the next step? Can I disconnect door sensors, boot sensor etc and if so how?

mibbe its the interior sensors rather than the basic 'door' sensors?

Same as mine. Every time the sun comes out from behind a cloud it goes off :|

Is there any bi-metallic strip sensors in the alarm system that could be at fault/corroded etc? The heat obviously makes the two metals expand at different rates, so the warm weather could be causing a sensor to malfunction (asuming there is a bi-metallic sensor lol)

I've disabled the interior sensors in the past using the key turning in ignition trick and it makes no difference.

you need to press the lock/unlock button 5 times in the cabin to 'deactivate' the alarm...

Mine was doing the same today for the FiL lol he was less than amused.

Mines also been going off alot... Am I right in thinking the interior sensors work on air pressure?

Surely there must be a solution? Can the alarm just be disabled full stop?

Pull it out?

Bit fiddly to get to but not difficult.

I'd prefer to try and keep it but it'll be swapped for something else if it keeps playing up.

is this the alarm sensor for the door?

Still got this problem, not sure if anyone else has? Also how do I disconnet the boot sensor?
