Yes I think you are right about the power sounders function.
Well, I have taken it out for a drive and it is locked/alarmed...all quiet so far....
I will keep you updated; if the problem does turn out to be the power sounder then I will cut open the Bosch and see if I can change the batteries.

Debs
The unit is out, had to take the wiper arm off to do it.

It is the Black Bosch unit.
1st inspection it looks fine, no sign of any cracks or water ingress.
I cannot see through the material unfortunately.

I have left the other alarm sounder in place; I assume this is the normal alarm? If so then if the alarm goes off again I will know it is not the power sounder. (Please let me know if what I just said is right!).
I am leaving it for half an hour before reconnecting the battery, I am told this clears the fault memory in the ECU.

Debs...your a star!
I will be in there tomorrow all being well.

Nicads I have no trouble getting them, try a model shop, not a toyshop.
They have hundreds of types with different capacities and reasonably cheap.

I have just been looking around and found this on a website.

Quote.
Power Sounder (next to Wiper mechanism / under scuttle plate:- Most/all? fiitted with a GM unit (pcb and batteries in a 'potting' compound) - it's 'naff'. The water drain conveniently located directly over the rear of the unit and the connector. The potting seal 'cracks' over period of time, and does an excellent job of retaining ingressed water. Remove and silicone it before it goes into 'when i feel like it - I'm gonna go off - day or night' mode. Fit a cut up coke bottle bottom over top of unit as a water deflector. Other models fitted with a Bosch unit - fails as well due to overheating batteries causing track & solder pad failure - can at least be repaired - will last forever if batteries raised away from pcb & airvents
drilled (fit the coke bottle)."

OK…update on the tailgate switch.
After I disconnected it I had no more alarms yesterday or through the night.
Took it for a run today, parked up, no alarms for 1 hour or so, went back to the car, unlocked, then locked it, 5mins later ….you guessed…the alarm went off.
Since then I have ad 2 other runs and she has now been parked up for 2 hours with no false alarms.
So it is a bit unsure at the moment. :-/
I will update as this unfolds.
A friend of mine recons it could be an ECU problem because all the alarms on the Omegas are linked through it….any thoughts on that?

Deb and guys, thanks for your input.
Since I removed the tailgate switch it is quiet. :-?

But tomorrow will tell, when I take it out for a run, and then park up.
I will let you know how it goes, otherwise I will be into the power sounder :-/

Have not noticed the speed of the flash. Do you mean once it is set or during the 10 seconds or so?

Help!

I have a problem that has developed over the last 2 weeks.
I have an Omega Estate 2.2 (2001) model. (post facelift)
The alarm keeps going off, no reason I can see.
I have disabled the internal cabin sensors and it still does it.

But….not all the time.

If I go for a run it will do it, maybe 3 times then after 1 hour or so I can set it and no problem?

1)      Any ideas what to look for?
2)      Can I disable the alarm but still lock the car?
Some guidance would be gratefully received.
