Presumably this is the dreaded powersounder problem, but my car's alarm (lights and horn) has gone off on it's own a couple of times for no reason.  What is the procedure for removing it safely without compromising the central locking or immobiliser (if there is one)?

Just unplug & remove it .... that's it. 

The alarm can also be set off if the bonnet switch bracket is bent a little so the switch is barely making contact. You can prove it by unplugging the switch and see what happens, though this is usually a summer problem as the bonnet flexes in the heat.

Here is the guide to remove the dreaded Power sounder:

It isn't the dreaded powersounder problem. That problems is the internal batteries leak, cause a short circuit, and sets fire to the car.
Something is setting off your alarm. The usual culprit is the bracket which holds the bonnet alarm switch gradually bends downwards and allows the switch to open, setting off the alarm. Bend the bracket up a little and see if it cures the problem.

A faulty power sounder can activate the alarm. Been there, had that t-shirt

2 AM for me ,on the 13th  and the wiper arm would not come off 

does defective micro-switches not set the alarm off  door thinks it's open ?

I was lucky with mine, it chirped at me as I walked towards it in a car park. Ten minutes later it was removed. I did cut it in half to inspect and the weeping on the circuit board was very evident.

Thanks for all the replies, fortunately mine went off at 5.40am, and I had to get up at 5.45 anyway (who knew that Vauxhall invented Alexa all those years ago..!). Now it is providing an excuse to keep it securely tucked away inside out of the rain while I fix the problem . It did actually turn off with the fob once I was awake enough to press the correct button, so I am thinking microswitches are more likely than battery leakage. The history file suggests that the powersounder was changed a few years ago. I don't really like the idea of an under bonnet fire , so it will probably go anyway. If I'm lucky it might take me until April to fix it, once the salt is off the roads...

Take it off now then forget about it forever.

The under bonnet micro switch bracket that is attached to the PAS reservoir was definitely bent.  I haven't have to time to wrestle with the wiper arms to get the cover off and remove the powersounder yet, assuming that's where it is?

Ok, I've read the guide.  I assume that the powersounder is a different sound to the regular alarm which sounds the horn and sets off the hazard lights. All I heard before was the car horn, so does that rule out the powersounder.  It will come off anyway, and I will have my earmuffs ready for when I disconnect it.

The powersounder will set off the main alarm under some of its standard fault conditions. So still take it out.  But also unplug the bonnet sensor if it still goes off

Ok thanks, all was quiet last night thank goodness and I will spend some time tinkering over the festive period to make it safe.
