I bought a Vauxhall Omega Elite a month ago and its 1999, When then used for three days all was ok, then when not used for one day after those three days the battery was flat. So i therefore bought a new one. Just last week the car was used from Wednesday to Saturday, on the Sunday not used all day but it started off the key, then not used on Monday or Tuesday being yesterday the new battery is flat when i went to use the car this morning. On the computer and on the dashboard its not showing a fault on all electrical stuff (eg) so i think it maybe some thing within the system that its draining the battery. Please let me know if anyone has an answer for this problem, as i have not had a vauxhall before? It maybe that there is a common fault with this type of car. Please let me know A.S.A.P. Thank you.

Sounds like you have got an electrical drain of some kind going on.One of the most common items to drain your battery is a faulty powersounder or boot interior light switch not working properly and leaving the light on in the boot.To see if it is the powersounder follow this link http://www.omegaowners.com/forum/YaBB.pl?num=1220198611 To check if it is the boot light switch drop one of the rear seat backs and after you have locked the car see if there is any visible light.I hope that helps.

Thank you for your information, i just went onto the link you sent me and printed it off. Therefore i will wait now for my battery to charge fully and then check as you said the boot light when dropping down the rear seats. The next thing i will do is on the link with the power sounder when the weather is better, and trust me as i will let you know the outcome of the one issue to do and or the other, so THANKS AGAIN.

No problem I just hope it solves the situation.(If it isn't these two please don't blame me,I am only going on previous experience with my car)

[x300_jgr]

I would have no reason to blame you anyway. I CHECKED THE BOOT LIGHT and there is no problem with that at all, i got things prepared ready to take out the plug feed for the power sounder/alarm, and where the drain holes are on the scuttle cover then lifted to see inside the plug feed which is on the top of the power unit, its directly below the rubber drain hole. As be it seen it was saturated with water, hence this may be causing the problem. As you said though i will disconnect the power sounder etc and then cover all open ended connectors with polythene bag and insulation tape, hopefully then this is the cause of the battery being drained? I will when done let you know OK?

Thanks for the update hope it all goes well with the powersounder

Hi there, the power sounder has now been as you described been taken from it mount and then replaced back with the plug connectors not pluged in. So then the open ended electrical plugs were taped up and not in use for the power sounder and the attatched horn. This was done this morning and completed by 12 noon. Therefore as of todays date being 27 feb 10 i will not start the car for the next two days, and as stated before leaving the car for two days the battery is flat. So if my car starts on Tuesday 02/03/10 it then must be what you described, but if the battery is again flat it will then be another issue. I will let you know on or after that date if thats Ok?

Yep very well detailed 

[x300_jgr]

Thank you so much for saying how the info i sent you back was comprehensive, as I do like to explain with everything in detail, so thanks again. I will keep you updated.

Since as i described the battery problem i had and removed the Power Sounder as you mentioned, i have not had any problem started my car up till now. The next problem i have is running out nearly of petrol as the indicator on the dash was flashing, re-fuelled and now its missing. So as i aint got a manual for this car do you know where the fuel filter is located on my Vauxhall Omega Elite 1999 model? As its missing by it dragging up the mess from the bottom of the tank. Thank you.

[Hannah Judes Dad]

Glad to see the battery issue is solved  Just out of curiosity how much fuel have you put back in to the car? It's just that you may have a sticking float in the fuel tank and it will reset itself if enough fuel get underneath it to move it from the bottom of the tank(very similar to a toilet cistern) my car ran low on fuel once and i only put a £10's worth of fuel in it and the guage didn't move.Later that week I put in £40 and it sorted itself out.The fuel filter is located just in front of the fuel tank on the underside of the vehicle if you wish to change it.

[x300_jgr]

Thank you for your reply, as i put in £20 of petrol in it was still the same as before. However my friend called up on Saturday and found the problem, its not petrol its an HT Lead on number 1 plug as there was no spark. It was just coincidental that that lead was the problem not the fuel when it was running low. So as it be today i will buy a new lead and put it on, as i have prepared all the work ready for it to be replaced. Having done that i will keep you updated on this issue if thats ok?

I may be experiencing a similar problem - flat battery after a week of non-use but as it was dark and raining when I tried to start the car, haven't delved under bonnet yet.

What I do know however is that the powersounder makes no sound - hazards flash when activated (by alarm) but no deafening noise.

Having read the linked thread above, is it worthwhile disconnecting and taping up the powersounder THEN charging the battery to see if it holds charge before shelling out on new one?  :-?

If it comes to it can people recommend battery make/models for 3.0 Elite that doesn't go out very often please?

interesting i think i have this problem as well but not so severe, can anyone tell me do all omegas have power sounders as i have never heard a peep from mine (if i have one) but the battery going flat is an indication i do and if that is so does that mean i have an alarm!! the things you learn on oof!!!
