Strange Alarm

[Deadloud]

I've got a bit of a problem with the X Type alarm .. one I'd better fix soon as there are rumours of neighbours planning revenge, I've noticed curtains moving as I walk down the street, groups of angry people gathering on street corners and a large mound of wood with a central stake in it has appeared on the green ... ok, I'm dressing it up a bit but you get the idea. :P

 

A few days ago the alarm activated after the car had been stood for about 36 hours with no problems. I went out to it thinking the worst but there was nothing, so I reset the the alarm and went inside ... sure enough about 5 minutes later it started screaming for attention again. This time I got into the car and started it, the display said the passenger door was open, it wasn't, but make sure I opened and slammed it shut again ... message cleared and no more problems. Then this morning (Sunday) at 7.00am it went off again after being stood silently for about 18 hours, this time there was no message about any of the doors being open. I've rearmed it and it's been ok for the last hour.

Anyone got any ideas ? I usually lock the car using the double locking system, all windows are closed and there have been no '5 flash' error signals from the indicators on locking the car.

 

I'm now in that uneasy position of waiting and not knowing when and if it's going to wake the dead (and those neighbours) next.

Hi Steve,

 

I had a caravan like that  ---  not a popular thing to happen at 6.00am.  In the end I disconnected it!

 

However, you can't do that with a Jaguar.

 

Not being expert in electrics, I am having a guess that the computer needs some resetting so, first making sure you have the radio code, disconnect the battery for about 10 minutes and the reconnect.

 

Having trained as an accountant, I can remember that the cheapest option is the best, other than when you send in the bill.

 

Regards,

 

Peter.

The last time I saw this, the car was sensing an intermittent voltage drop caused by the Webasto.

 

Not that you have a Webasto of course but the principal is one worth exploring I'd think?

Ta, I'll try the reboot next time it happens ... so far today it's been fine (after this morning's episode). I've set up a camera with motion detection to check if a cat/fox etc might be causing the problem (no idea how sensitive the alarms are or even if they monitor knocks etc but worth a try).

Hoping it's an anomaly. Yep .. I have the radio code.

Just a thought...

 

Volumetric alarms can sometimes detect a dangly in the car. For example an air freshener hanging from the rear view mirror.

There's nothing like that in the car .... I despise anything dangly in the car ... always took the girlfriend home first! ... even satnavs have no place on the screen in my opinion. Always laugh at those who stick the satnav in the middle of the screen .. you could hide a truck behind that. These people are in the same category as the furry dice/air freshener on the mirror and 2 years worth of old carpark tickets brigade. Not fit to be on the road.

Well, from that I assume you don't have anything dangly in the car

Update. No further incidents since Sunday morning, I've deliberately not used the car to see if it misbehaved. (Nice motorbiking weather anyway). Finger's crossed.
