Alarm going off (Again)
Usual culprit is the bonnet switch, it's dead central just in front of the screen. Try disconnecting it and see if the false alarms stop.

This couldn't be a relay or component issue in the module could it? I seem to recall hearing about that once.

Can't remember if this is true or not but i read somewhere that if you lock the car with two clicks of the lock button doesn't it deactivate the alarm? Not a fix as such but might help in the short term.

A poor connection could trigger the alarm without storing a code, as it could be seen as a genuine trigger rather than a fault.Marc-j wrote:I think it deactivated the tilt and interior sensor. I did that before and the tilt sensor was still triggering the alarm.
But it has got me thinking... despite being disabled via coding the tilt sensor was still triggering the alarm. Upon inspection it the connector was fairly heavily oxidised. Replacing the tilt sensor seemed to cure it but now it has come back, although it is now seemingly random rather than a constant straight after locking.
I am thinking that perhaps removing 1/2 of the oxidised side of the connection by replacing the tilt sensor only improved it instead of cured it. The oxidisation is causing some kind of unknown error outside of tilt sensor malfunction (fluctuating current?) which is why there are no codes in the general module.
Or am I clutching at straws

Well worth cleaning anything corroded. Not sure if there is a loom repair kit for that connector.

Alarm going off (Again) not bonnet sensor
My alarm keeps going off randomly. Its very annoying, especially in the middle of the night. I read the codes and it seemed to be caused by the interior sensor. So I'm going to get this disabled next week, but in the meantime I've been locking the car with the key, rather than the remote, so the alarm isn't armed.

Low voltage can defo do it, just as disconnecting the battery without disarming can.
