    Alarm Grief

    Last week my alarm on my Mk4 Sri was playing up, it would randomly go off. The LED above the hazard warning light was flashing when you set it which meant a fault. I got the power sounder replaced and it was fine.

    Now itís been randomly going off, full on horn and hazards flashing. Thatís twice itís gone off since lunch time now and work aint too happy about it all.

    Iím taking up to the garage tomorrow to plug it in again but I doubt they will find anything.

    Now the power sounder has been changed out is there anything else I can look at or change.

    If its gonna remain going off its no use as im away from home for long periods of time, I might have to think about disabling it and putting in an aftermarket one.

    Any ideas?

    I'd wait until they plug it in to see what it's going off on. The alarm system is part of the central locking unit so can't be removed

    The back-up batteries in the alarm power sounder seem to have a very short life. I've got through 3 power sounders in under 6 years, 76,000 miles.

    In my opinion, a part which won't last 2 years, or 20,000 miles, should be changed every service but Vauxhall won't do that as it makes the cars look expensive to service, compared to other brands.

    if u take to vox they can check the alarm codes and it will show what has been the cause or area of problems...

    astra g's like osf pin switches from time to time....also check bonnet switch.. etc...

    door ones couple a quid each...cheap try if you dont want garage bills..

    vox will intially charge you .6 labour for diagnostics...just over half hour...

    if u get a chirp form time to tiem or when u get in and turn ign on...its the powersounder mate.

    hope helps chris

    Turns out its the "pane break sensor" wherever or whatever that is.

    Apparently the alarm thinks the window has been smashed, but obviously it hasnt.

    Why would it require a new window? Its quite obviously not smashed or cracked.

    Does it only work wih the back window or all of them?

    it may just be the connections to it....but have changed glass due to faults that wouldnt go away..norm there is a sensor/wiring in the glass..

    did they say which one?..

    is it the rear quarter windows?..check your wiring to it...thing is with the tom tuter you can identify when checking connections if fault goes away, i.e not present....your gona have to do it a bit blind so to speak...

    if you can check for any obvious wiring prob or even bridge it and test and see if it stops the fault...then you can tell which is causing prob and go form there mate.
