Omega General Help / Re: Omega Alarm problem. (Help needed.)

« on: 26 October 2011, 15:00:00 »

Hi to all,

I honestly can't believe it but it looks like the wire trick has worked.

I wore a pair a 3x magnification glasses and traced the entire length of the filament on both sides of the car. The break wire looked to be in perfect condition. I then disconnected the two connectors and looked at their size. I found a bolt of a similar size, cut two pieces about 6 to 8mm long and simply joined the two female ends of the connectors together using the small piece of bolt as a male/male connector. It looks neat, I haven't had to cut anything and there are no additional connectors or wires.

The alarm hasn't sounded in a couple of days now and I'm chuffed to bits.

Once again, thanks to everyone.

If only I can get my computer to work properly now!

Thanks guys,

I really appreciate you all getting back to me.

The alarm situation is driving me nuts.
It's not so much the alarm going off, which is really annoying, although I can over come this by engaging the central locking via the drivers door latch.

It's the fact that I can't find the fault.

First thing in the morning I will wire up the rear window security strips and see if that works.

The strips look fine, but they may well be the issue. Failing that I'll take it have the alarm codes read.

Once again, thanks to everyone for their comments.

Richy.

Hello again,

It seems like problems come along in groups. My computer took a fit and I haven't been able to log back into the owners club site to update.

I've already disconnected the power sounder battery as I'd said in my first post. This stopped the alarm going off "for no apparent reason" for a number of months.
Then the alarm began to go off again after the power sounder disconnection.

I've checked, cleaned and reconnected the break glass connections on the rear (estate) windows. I cannot see any "obvious" fault here.
The alarm continued to go off.

I disconnected the bonnet switch.
The alarm continues to go off.

So I ruled this out. I've removed the bonnet switch bracket, filed and slotted the holes. I made sure the switch made a good contact with the bonnet when closed and I refitted the bonnet switch.

I've closed all the climate control vents, engaged the internal sensor disable switch. Re-checked the break glass connectors and re-checked the bonnet switch. I've blown the dust out of what I assume to be the cabin ultra sonic sensors. I've made sure all the windows are closed and that the boot lid is shut properly.

And... Halfway through writting this post (seriously, I was and it has)

The alarm has just gone off again. Although this time it took about 3 hours from arming the alarm to it going off.

I honestly haven't got a clue what on earth could be causing this. Do I need to take the car in to a dealer?

Can anyone help?

Thanks to all,

I'll check the bonnet switch and if by the sensor on the back the window you are refering to the sprung loaded electrical pin contacts I'll give them a rub over and check the contacts. If this isn't what you mean by sensor on the rear windows could you enlighten me please?

I'll see what happens with this first and then I'll try the internal sensor disable button. Are there any tips for this? Should I just press the button before I get out and lock the car? I don't want to sound dim, but there is often a method that works better than others. (As in: quarter turn key, press button, turn key back, put your credit card pin number into the radio, sacrifice first born son and stand well back sort of thing.)

It's not a major problem and I can overcome it by using the back door technique to engage the central locking, but it's a real pain and I'd like to be able to use the key fob again as once I'd disconnected the battery from the power sounder it was really nice to be able to open and lock the car normally.

Once again thanks to all who replied and without forum sites like this I don't know where we'd be. I've spoken to pals who are mechanically minded and they just went blank when I mentioned the power sounder battery problem. Without "Omega Owners" I'd still be stumped.

Kind regards,

Richy.

Omega General Help / Omega Alarm problem. (Help needed.)

Hi there,

This is my first post so please be gentle. I have 2001, Vauxhall Omega, 2.2 petrol, CD, Automatic, Estate.

I've found the forum very helpfull and have generally found the answer to any question I've had in the posts, but now I have a problem I simply can't resolve.

Over the past 2 years I had the age old issue with the alarm going off whenever it decided to. I got past this by simply locking the car when I'd parked up by opening the rear drivers side door and depressing the button catch in the door to engage the central locking then closing the door and the car would be locked without using the remote key fob or engaging the alarm.

Then I read about the power sounder on this site and figured this must be the problem. So I set about disconnecting it and once the deed was done the alarm system worked perfectly once again. I could use the key fob to lock the car, engage the alarm/immobiliser and I no longer had any troble with the alarm going off at silly hours and for no reason.

However about 2 month ago I decided it was time to sell my beloved Omega and move on to something else. The car sat on my friends drive while I waited for a buyer to come along and the car was turned over, but not driven (as I had transferred my insurance NCB) on 2 to 3 week basis. Then about 2 weeks ago when I locked the car, the alarm went off almost immediately. I didn't think more of it as I put this down to lack of charge in the battery.

Anyway, I've decided to keep my Omega and got it re-insured and took it out for a drive today, confident that the run would resolve the alarm issue as the battery would get a decent charge. When I parked up I used the key fob to lock the car and the alarm went off straight away. I can't find any issue with the bonnet catch and the battery seems fine. As I said the power sounder is disconnected and still the alarm goes off. There isn't a delay of more than a minute or two from the key fob being used to lock the car to the alarm going off.

Can anyone help?

I'm back to using the back door locking method once again as I simply can't find the fault.

Many thanks,

Richy.
 
(I loved the Omega so much that I've decided to keep it and sell the Audi A6 3.0 tdi V6, Quattro, SE, Tiptronic, Saloon I bought to replace the Omega with. Does that make make me mad? I just find the Omega more refined and more practicle with it being an estate. The Omega has better seats, driving position and visibility than the much more expensive Audi.)
