I have a 2000 v reg omega 2.o litre cdx. I want to reset the managment unit but everytime i disconnect the battary the alarm keeps sounding help how do i stop the alarm

[dbug]

Disconnect battery within 15 seconds of turning ignition off

Thanks just read that in the drivers manual 

Next question and this one is a bit harder. 

Stopped the car and put the gearshift in park then all the dash lights failed. All of them. then on the right hand side of the dash there was smoke and a burning smell of rubber or plastic. when i went to start the engine again it came up with a automatic transmission fault and went into limp home mode. Any ideas as to what could have been burning?

The 'power sounder' ie the battery back up alarm siren, lives under the plastic scuttle on the driver's side of the car. It's not unheard of for them to set on fire. It does sound like yours has burnt out, perhaps taking something else out with it.

This being the case wouldn't the alarm be silent when disconnected from the battary? Because it isn't it still sounds when we disconnect the battary  :-/

Any other ideas what it could be? I will rip the dash out if i have to be i would rather not

No, it has it's own internal batteries.

The clue was in the description ....... battery & back up

ok do i have to take the dash apart to get to the 'power sounder' or can i just remove the instrument panel?

Sorry for asking so many questions but i have only had this car three weeks.

No need to disturb anything inside the car. It lives under the o/s off the scuttle panel. Under the wipers. I think there may be a guide somewhere.

The power sounder lives here..... http://www.omegaowners.com/forum/YaBB.pl?num=1220198611 and if you feel you want to have a go at replacing the internal batteries then that guide is here ..... http://www.omegaowners.com/forum/YaBB.pl?num=1240077701

Ok so why would this cause smoke within the car and not outside the car and why would this cause me to lose all the instrument illumination?

Andyb you said it may have taken something else with it on an earlier post any ideas as to what may have gone with it?

[Kevin Wood]

Have you checked all the fuses are intact?

Whilst the power sounder can cause a fire and, unless recently replaced, is certainly better off out of the car than installed in it, if you had smoke from under the dash, then something under the dash was burning. This may or may not have been related to the power sounder (the wiring from it may have overheated) but it certainly merits an inspection of the wiring under the dash.

If a fuse has gone it's a good indication what circuit might have been at fault.

In any case, disconnecting the battery doesn't "reset" an Omega ECU in any sense. They have non-volatile memory.

Well in the meantime we have disconnected the battary mainly to cut the circuit of power incase it sparks off another fire. We have decided to pull that power sounder off the car we are going to do the dash tomorrow. I am starting to wish i had never bought the car  :-/

Cannot access power sounder by removing dash....

I know it says that on an earlier post i have even been given the link on how to do that.

Does no-one ever read the threads from the beginning around here

I need to remove the dash to see what else is burned out with it. I have no instrument illumination it has all gone. I also have a warning stating "Automatic gearbox" when i start the car up. It is also in "Limp home mode"
