xantia HDI year 2000 Alarm goes off!

Post by johntech »

Hello everyone.
I bought my Xantia a year ago 35000 miles everything has been fine until last week when the alarm went off at night for no reason.
I reset and half an hour latter same thing happened!
So I left car unlocked and went to bed. The following day I checked the sensors for spiders etc. everything seemed ok. Rearmed the system half an hour or so latter alarm sounded again.
I am an electrician but alarm wiring is not shown in the manuals I have.
Has anyone had experience of this fault? If all else fails is there an easy way to disable the system so I can still lock with the plip?
Any info greatfully received.
Thanks John

If you try disabling the volumetric sensors first (see handbook :) ), it will at least narrow down the possibilities.

I think it is a common problem as the cars age. The ultrasonic sensors get over sensitive as they age. Had the problem on my XM when I got it. Got a new pair of sensors from the stealers and it has never had a false alarm since (3+ years). They were surprisingly cheap I seem to recall - £25 mark - I expected them to be more.
Cheers,
Rowan.
