Yes ANOTHER question, i'm on quickfire today!

Just been disturbed by my car alarm going off. Went to check and everything was okay... then went back in the house and 10 minutes later it went off again.

Now random alarms i am used to. My corsa used to do the same...

What is it with OEM alarms that makes them so cruddy? I know my examples are french and pauxhall but still what makes them randomly go off?

This 3rd time, i've just given the car a run, and turned off the interior sensors (incase its a spider or something)

Starting to wonder however, what other sensors there are!

Any suggestions to the above?

Bad earths or Batteries on their way out are the usual. Unless you have a motion sensor in the car and a thing dangling from the rear view mirror. You don't have an open window and a bat flying about? biggrin

Pretty certain on the rest but the bat has got me thinking, i've never noticed a bat in my car but i guess they only come out at night..


hmmm


And since turning the interior sensors off, the alarm has stayed quiet. So if the bat is flying about causing mischief, then the alarm wouldnt go off

weird huh?

hehe

You may have a homeless person living in the boot, probably a TVR owner. hehe

I have been told previously that open air vents can set off internal sensors?

One one of my dads old cars the alarm would go off on a Sunday morning, this turned out to be that this was normally the only time the car sat on the drive for a long time (work during the week, busy on Saturdays), as the sun hit the bonnet the metal would warm and expand slightly, just enough to lift it off of the switch that protected the bonnet (which was misaligned), thus setting the alarm off.
Once the switch was re-aligned it was fine.

You should try living with a current model Lancer, Mitsubishi UK fit some hoopy CANBUS based Cobra alarm. It goes off if it rains, it goes off if it's sunny, it definitely goes off if it's windy, it goes off when someone drives by, and it even goes off while driving down the road. Piece of crap.
