Can anyone help me, the alarm on my omega keeps going off for no reason, have disconected the battery at has stopped for now but as soon as i re-connect the battery its going off again.  Any idea what is causing this and any solutions?

Cheers.
Rick.

Disconnect the bonnet switch first, then try. If fault persists i have heard that the Power sounders play up on the Facelifts. It may require stripping, cleaning and the battery replacing.

Hello sounds like the bonnet switch as Dazzler suggests   Is it doing it when the sun gets on the car mine only did it when the car got hot sat in the sun  :-? if thats the case it more than likely is the bonnet switch. Lift up the bonnet locate the switch on the 98 2.5s there is a braket on the power steering resivoir this holds the switch not sure if its the same on yours . Either try adjusting the braket or as I did and others have pack the contact point of the switch out on the underside of the bonnet and see if that cures the problem it did mine

Hi,

Thanks for the info guys, just to update the alarm itself goes off once its the power sounder that keeps on going, where can i disconnect the power sounder?

Thanks
Rick.

You need to remove the scuttle panel and it's then on the driver's side on a bracket on the back of the suspension turret.

It does sound exactly like the symptoms I had. The batteries inside the unit had leaked and damaged the circuit board.
