996 Constant beeping

[RRH]

Hi all.

Every time I turn the ignition off, I get a chirp from the alarm- approximately every ten seconds.

This started after the alarm went off at 4am this morning, I disconnected the battery eventually but when I've re-connected it its started again.

It stops when I start the car.

I've checked the glove box / cubby / all doors / front boot and engine cover, all seem ok.

Any ideas?

Thanks

My guess is the battery on the way out - easy test and resolve.

Whilst that is logical, the battery doesn’t seem at all lazy. Is it worth leaving the ctec on it? It’s probably not been started in a fortnight, it is starting no problem though?

The horn ‘chirp’ is usually an open glovebox, door or bonnet. If they’re all closed, then I can only imagine it’s a battery that needs changing....

Hi I would suspect alarm siren battery failure.

The beeping when locking is as others have said, but your fault is when turning ignition of, not locking the car.

Ok, thanks for your help everyone.

I removed the siren yesterday to eliminate that- obviously it’s not chirping now- I’m not entirely sure what I’ve proved by that but at least I didn’t have to disconnect the battery (I did this at work yesterday to stop it chirping- slammed the front boot- ffs- then had to call the AA to get me back in. Idiot).

I’ll put a meter on the battery this morning and see how it’s looking after a night on charge.

Thanks again.

Surely the answer is to get the fault codes checked and see what the car thinks is wrong?

[RRH]

I got that done yesterday, It’s not showing any codes whatsoever!

Mine did this with a door or the frunk open. When the battery was dying the alarm used to go off. One of the neighbours once came round at 10.30pm to yell at me about it. He got very exercised about the whole thing....
