Been to garage today and they put it on computer and all they could suggest was to take out alarm fuse. .... There isn't one from what I can see! The alarm did go off on the afternoon before the horn started in the evening-it had a funny five minutes with the heated windscreens etc and petrol left computer etc going bananas but they were rectified by taking the battery off-put horn fuse back in and it was ok for an hour then it started again-very loud! I just don't understand how it turns off with the ignition?

the alarm uses the horn sounder i think what you describe is what happens when the car is locked and alarm activated if you open the door with the key and not a remote then the alarm goes off till you put the key in the ignition and switch ignition to pos 2 which is what this sounds like

why i can only assume that youre using the key to open the door if not theres an electrical fault somewhere that will have to be traced does the interior light switch off if not a door sensors faulty the boot sensor could be faulty or theres water got into the electrics youll need daylight to see but it looks like youll have to get an auto electrician at it

The alarm has it's own horn, the module is up under the front scuttle against the firewall bulkhead.
I'd say water in the fusebox or a bad earth but seeing how bad the weather has been I'd be more inclined to say water ingress.

If you manually unlock your car using the key blade rather than remote unlocking then the car will beep and then sound the alarm until the key is in the ignition and at II thus interrogating the key and verifying that the correct PATS transponder is present.

I'm using the remote to open and lock. I've looked at the fuse boxes and they seem dry-I was thinking it would be a rain getting in somewhere problem-maybe? I'm sorry but I don't know what bulkhead etc is lol-im living up to being a blonde woman! :wacko:

The firewall bulkhead is the panel between the engine and your footwell.

I still suspect water somewhere or even a rusty earth point somewhere.

Give a couple of car electricians in your area a call to see how much they would charge to have a look for you.

Ok I'll do that, hope it's not gonna be expensive! Do you think the fact my drive is quite steep and car is spending a lot of time at an angle is possibly adding to the possible water ingress? :blink:

Bugger! It's been ok through this !Removed! weather so I figured it had rectified itself but maybe I've just had my head in the sand! Time for some detective work!
