Xantia Alarm

Most likely to be the ultrasonic detectors built into the driver and passenger doors (on the inside of where the mirrors are) try disabling the ultrasonic detectors on the dash and see if it makes a difference. If not take the car to a Citroen dealer and ask them to read the fault codes for the alarm. (which would probably be a good idea in the first place)

I think most people disable the alarms on Xantia's after a couple of years due to persistent problems!

Someone has disconnected the siren on mine, and I have now totally disabled the alarm (which is quite easy) because I got fed up of the lights flashing!

There's a key switch under the bonnet to do that...

Not on all Xantias, my early series 1 VSX had the keyswitch, my Activa has a great big fat nothing there :)

(btw, my alarm works fine, take it to a sensible dealer/specialist and they will fix it no problem, both of my Xantias have had the ultrasound detectors fail and replacing them fixed the problem costing about 50 quid inc. parts and labour for each car)

Don't set the alarm is the obvious answer ;)

If there is no key switch to disable the alarm system under the bonnet at the top right hand side (it looks like a door lock) then there will be a button in the cabin, (somewhere on the right hand side of the steering wheel if my memory serves me correctly) which has a picture of a siren with a cross through it, if you push this button in then it will disable the siren (you may have to hold it in for 3 or 4 seconds to enable it, i don't fully recall) but you will have to do this every time you park the car and stop the engine.

You can disable to alarm permanently by using the alarm button to the right of the steering wheel.

Start the car - possibly with the alarm going! and press and hold the button in for about 5 seconds. The hazard warning lights will flash five times in a row very quickly and the alarm will now be totally disabled. You will only have to repeat this procedure if you disconnect the battery. That's what I have done and I have never had to re-do it everytime I lock the vehicle.

Umm, that doesn't disable the siren - it disables the ultrasonic sensors only.

I don't know about the various iterations of Xant alarm, but on the s2 XM (which had the same style as the '93 and '96 Xants my parents have had), you just either use the key, or only give a press on the first remote button - one is lock/unlock, the other sets deadlocks and alarm.

Yeah, reading the other post i got confused about that and the disable by holding it in for 5 seconds. Most Xantia alarm problems tend to be found to be the ultrasounders which is why I was confusing the situation. Testing this by disabling them tends to show up the fault.

Aye, when my car had a faulty alarm i just never deadlocked it. Like anyone would want to nick a citroen in the first place ;)

With the ignition off, yes. Doing it with the ignition *ON* will disable the siren (series 2 Xantia, '98 on....)

The control box is under the carpet beneath the front passenger seat (UK spec cars anyway). Try disconnecting it to see if that shuts it up.

Sorry, don't know where the siren is, probably behind the bumber or somewhere just as unlikely.

I don't understand why you can't just disable it as I have mine with the dashboard button.
