Omega General Help / Re: Diesel Problems; Please Help

« on: 27 May 2013, 10:28:36 »

which side of the engine is the leak on? how many miles on the clock?

Thanks!  Car has 168,000 on it. The leak seems to be coming from the drivers side, from somewhere under the alternator. Could it be an oil pressure switch?

Hi, check all your vac pipes, also the rubber elbows on the vac pipes as if they are gone they will let air in. the one at the back of the head is a sod to get to but gets hot back there and is normaly the first to go. you can pop the EGR off in about 5mins so have a look and clean carbon off it at the same time, you will see the inlet manifold has a lot of carbon inside aswell but that would take you a few hours and two new inlet manifold gaskets. you can check the EGR valve is working when you have it out just hold it to you face and push the piston in, it will suck one side and blow the other, they are not electronic on the Omega. there is a valve on the turbo that goes but can't remember the name at the moment, do a searh and have a good read i know i have seen it. hope this helps

Hi! Thanks for that. You wouldn't happen to know where the EGR vavle is? I was looking for it yesterday but dammed if I could find it lol

Omega General Help / Tow-bar wiring for Omega B

« on: 26 May 2013, 23:43:10 »

Hi,
Having a tow-bar fitted to my Omega this week (would have had it last week only the company sent me the wrong one).

Having concerns about wiring it, I've read somewhere that the brake lights need wired through some special box behind the glove box?
However i have also read this on the Vauxhall owners club:
"the Omega and Cavalier, both have a plug in the boot. With the Omega, I had to put an extra fuse in, to power the plug."
Which is most likely to be the case? My father (who is a mechanic) has every hope that its just like wiring any other tow-bar, however I'm not so sure 

Anybody have any ideas?

Thanks!

Having some issues with my 2.2 dti. When accelerating there is a slight miss miss with the turbo, alongside this there is a whistling noise when revving about 2500rpm. At first I thought the turbo had had it, but had a mechanic check it out and he says the turbo is fine and cant establish a reason as to why the car is behaving this way.
Could there be a link to the EGR valve? Slightly worried as I'm going away with the caravan in a couple of weeks and would hate to break down.

p.s. There is an oil leak from somewhere near the bottom of the engine, haven't established where exactly its coming from, but could this be linked to my problems?

Any advice would be appreciated!

Thanks!

Chances are if it is darting around all over the place, that the rear bushes on the lower arms are shot Classic symptoms tbh

Either replace the arms with new or refit the rear bushes with genuine vx ones, £20 each. If the front bushes are split, cut them out and replace with poly ones from Powerflex

All in the Maintenance Guides

Save the alignment until the problem is sorted

Super Advice! Thanks

Omega General Help / Re: Heated Seats Blowing Fuses?!

« on: 11 April 2013, 00:40:13 »

Had a good look and play with the seats today.., drivers heated seat doesn't work.  However, every now and again it will blow the fuse for the instrument cluster (fuse no.15) if you try turn it on. I checked under the seat to check wires, they all looked fine. Was going to check the connector, but didn't know what it was and didn't want to be to carefree in my investigation in case I disrupted an air bag or something. 

Anybody have any idea what would be causing this? surely if it was a problem with the seat connections it would blow fuse no.14? yes; no?? 

Thanks,

Yep. 99.9% certain you`ll find that the feed to the seat heater module has been chaffed resulting in shorting out on the seat frame. (Cable lives behind one of the seat motors so tricky to spot the damage)

Thanks! This might be a silly question, but can chaffed wires be repaired?

Im having a similar problem with my Omega.. 

When I bought the car both front tyres were bald on the inside, and the steering was a nightmare when driving. The car lurched all over the road, and i had to fight toe steering wheel to keep it going in a straight line.

Put 2 new tyres on the car. My dad has some 'old' wheel alignment tools (they borderline on being antique), and according to them the alignment was perfect.

Took the car out for the first time last night and the steering was just as bad. When breaking the car darts across the road and when you go over a bump the car skittles about.

I've had all the wheel components checked and can see nothing wrong with them. Would having the wheels professionally realigned solve the problem or is there something ive missed in my checks?

Is there any easy to check the wiring?

I know that the pads can burn out, and cant be replaced.

I considered disconnecting the drivers heated seat and just leaving the passengers one as it doest seem to be causing any trouble (yet). Would that perhaps help the problem?

Omega General Help / Heated Seats Blowing Fuses?!

« on: 09 April 2013, 23:35:48 »

Hi, I have an 03 Omega 2.2 Dti.

When I first got the car I had problems with the instrument cluster, however this turned out to be a simple fuse.

However I have now discovered that the heated seats are blowing the fuses. Got into the car tonight and put the heated seat on. Turned it off after a minute or 2, and then decided to keep it on. As soon as I turned it on, the cluster went dead. I checked the fuses, and sure enough the fuse for the instrument cluster was blown (think it is fuse no. 15).

Was out later on in the car and my dad put on the passenger heated seat and there was no problems. Does anyone have any ideas on what could be causing this? Perhaps the fuses are to low (or maybe to high)?

Any advice would be appreciated!

Thanks,
Garrath

Hi, So sorry it has taken me to long to update you on this! I bought a new cluster on ebay costing me £60! Fitted it with great excitement only to discover that it hadn't solved the problem. Of course it turned out to be a simple fuse (which I apparently already checked!).

New fuse put in and cluster works perfectly!

Thanks for all your advice!

 

P.s this forum is much better than the forum I joined when I drove a Peugeot!

Omega Electrical and Audio Help / Speedo Cluster failure

« on: 16 January 2013, 15:12:15 »

Hi, Newbie here  ,
I recently bought a 2003 2.2 CD DTI. When driving the car home the entire speedo cluster stopped working (inc. temp and fuel gauge). None of the service lights seem to work either, meaning that when the ignition is turned on, the dash cluster is completely blank, although the full beam, indicator and fog light icons still light. This problem is intermittent as when the car is left for a while, everything works when I return, however will fail in 5 mins or so.

I have researched and discovered that the problem can be related to the ABS, however my ABS light is off and ABS still works.

Any suggestions or help would be appreciated!
Thanks!
Garrath.
