Alarm keeps going off

[Kierandc5]

So when I park the car and lock it within about 30 seconds the alarm goes off and I could repeat this process 2-3 times. Any ideas?

Under bonnet alarm switch , disconnect & try without to know for sure

Where is this switch located. I was thinking along the lines of the battery was on its way out etc

Bonnet up stand central looking up to the wipers . It's located where the 2 diagonal strut braces meet the bulkhead

Had this on my old E85 and it was the under bonnet alarm switch.
IIRC if you double click the lock button on your key it will disable the Alarm. Might be handy until you get it fixed.

Yep had the same problem on my last Z, under the bonnet switch as the others have said, luckily, easy enough to replace

Atleast it's Nothing serious. Just embarrassing

Mine kept doing it at work...it became a bit of a running joke and gave the bosses another reason to take the mick out of the Z (only jealous). I just removed the sensor as mentioned above and gave it a good clean etc and all has been fine since.

I should have electrical cleaner still floating about. Will give it a clean and with some luck be good. If not I'll just disconnect until I order the part

Mine was the same, under bonnet alarm switch. I've just unplugged it and left it at that, problem solved!

Double clicking the lock key disables the interior and tilt sensors, not the perimeter alarm, so the bonnet switch isn't excluded. Mine did this, stripped the switch and cleaned it, been fine since.

Just an update, disconnected the sensor and all is well. Im going to strip down and see if it can be fixed, if not then I'll just go without the sensor full stop
