Hi all, does anyone know the acceptable tolerance on Omega level (Elite with self leveling suspension). What I mean is when measuring from the ground to the under side of the wheel arch lip on one side compared to the other how far out can it be before you should be concerned. :P
I assume the pressure to both shocks would be regulated equally and balanced. :-?
Also, am I right in thinking that as long as the shocks don't leak they are in good order. I have also carried out the bounce check and it just goes down, then up, then stabilises instantly on both sides.
Any comments welcome. :)
Mike.

I can only give you the measurmenst from mine which has recently had new GM shocks and YYB s/l springs.
Ignition off and car parked....665mm from ground thro centre wheel to underside of arch.
Ignition on and pump running...680mm
When ignition turned off and after a few mins car returns to 665mm
Assume alot of it is goverened by how much weight you have in the boot....mine is full to bursting with door/wood samples and brochures...I plan furniture.
Hope that helps.
-
Thanks for that. How much discrepancy do you get from one side to the other if any? :-?
My passenger side measurement is 680mm and the drivers side is 705mm (boot empty and ignition off).
I have just fitted new rear coil springs and the shocks showed no signs of leakage.
-
Both sides of car sit level so if you have a variants between sides I would either be expecting ..broken rear spring/defective shock/leak in air line to shock.
It may be worth trying this.
Turn ignition on and let car and pump set ride height.Switch off ignition and remove both air lines from the shocks so you release all stored air.Measure again to see if the back is level.If not the fault is as above but not the air line.
The compressor can only pump air whilst the sensor on the diff tells it to by recognising the height.
What measurements do you have then with the pump dissabled and air lines removed ?
-
.... and remove both air lines from the shocks so you release all stored air. ...
Each side of the car is T'd off from a single line to/from the compressor up front, so disconnecting any of the joints will reslt in the loss of pressure in all the sysytem.

As Andy says. Doesn't matter where the air is released, ie just one shock air connector will do.
But yes, let the car settle on the springs only as a start then go from there.

Guys,Just curious to know what the height of the rear end goes to when the s/l pump cuts in,and how long after switching of the ignition does it take for car to go back to settled position.
Reason I ask is have just fitted s/hand pump and level sensor and have made a note of the ride heights before bits changed and now after replacing,but would like to compare with others cars.
-
Depends how efficient the pump is. It will top out after two or three minutes ime. Long enough to possibly flatten the battery with ignition only. The system will raise a fault code if it's running that long and I suspect it may well time out as it suspects a leak.
It's quicker going down again. As mine is disconnected I can't test it. I didn't time it ::) so only guessing. If it operates through the range I really wouldnt worry. :y
-
I have no real concernes with it now just curious as to what is regarded as the correct height.
Front measures up at 665mm...back is 665mm with ignition turned off and settled for some hours.When ignition turned on and engine/pump starts car raises to 695mm and tends to stay there.When ignition is then turned off and car left for say 1 hour thre is no difference to ride height at back..still at 695mm.
If left overnight car,s rear end returns to 665mm.
Reasons I noticed this was driving on motorway the other day I had to adjust both door mirrors as they seemed to be wrong against the visual position of the cars rear,so investigated and found back sits around 35mm higher than front when running.
Thought idea was to keep car level with the front measurements.
-
Hi all, thanks first of all, for all the constructive info.
I think I may have become a bit paranoid about this issue but it isn't until you change something like I did (fitted new S/L springs fitted) that you start to focus in on minor details.
I went out in mine yesterday and found a piece of ground as near perfect level as I could and with the engine running again measured the height to the underside of the wheel arch lip through the centre of the rear wheel from the ground and gladly found the measurement to be the same both sides 27.25" (692mm). I turned the car off and returned approx. 1 hour later - the measurement was again checked and found to be the same. :) I suspect now the original discrepancy is due to the fall/chamber on my driveway :P
Regarding the last posting relating to level and how the car sits on the road I would suspect that it would be normal for the car to sit slightly higher at the back for weight distribution, handling and braking characteristics to be achieved. I also, understand that the self leveling system is important with regard to Elite Xenon (HID) head light alignment.

Two quite separate beasts. ;) ;) ;) You can have either one without the other, the HIDs have leveling sensors on the front & rear near side suspension, while the self leveling suspension has a sensor on the driver's side rear radius arm. :y
-
I think I will join you in the paranoid state !!!
Your measurements seem to be pretty consistant with mine so think you and I can assume are cars are either correct or atleast identical ,which ever that might be for the better.
Intersting to know what the rear end height is with engine say switched off over night or a longer period than 1 hour.I find that the rear end does infact settle down to that of the front which is 665mm overnight so the retained air in the system must slowly be discharged ? Would have expected it to return to that of the front much quicker though...paranoia taking over again.

May help further

Sorry for using this thread for info. I talked to previous owner of my omega and he told me that he disconected the suspension leveling compressor because he was "playing" with it to see if it works, pumped to the highest point and then it didn't drop down on previous height. I assume he just didn't wait long enough for suspension to lower down. He then manualy released the air out till it was sitting on springs and disconected compressor.
-
If this helps at all .... on mine if I load up heavy then the pump will run and the system will rise back to "normal" height as expected. If I then "unload" with the engine off it will end up sitting "high". If I leave it overnight it will still be "high" in the morning, but as soon as I start the engine the system will "lower" it to the normal ride height.
:)
-
What I would like to know is where is the compressor and would it be ok if I reconnect it? Thank you
-
Compressor is under the front right hand wing, behind the headlight. You need to remove the wheel arch lining to get access to it.
As to reconnecting I suppose it depends on the condition ... if its not been used and is all corroded ... probbably not a good idea ... might be better off getting a known working one from a breakers ??
-
Thanks, at least it works, in a way. I'm curius if it still works on mine omega. I know curiosity killed the cat but.....you know :-/
-
There's the problem. No omegas elite in Slovenia, I believe mine is the only one "sport" edition and even this was imported from germany.
-

You'll be able to reconnect you compressor from under the front of your car without removing the inner wing ..... I did (the car was on ramps ;)). Mine was disconnected when I bought my car (years ago) and all was well when plugged back in. :y
-
Is there any other way to see if it works maybe? :-[
-
Thanks!!! :y ;D
-
I'm not sure what engine or spec your car is but on the diesel Elite's the pump is halfway under the floorpan where's the V6's have it behind the front bumper / wing.
-
We have bad weather here resulting in slow conection and all posts I get with a delay(as my train I'm waiting for- 126min late) sorry for confusing answers. I
-

you could try to reconnect power with the pipes disconnected just to check the compressor runs .. this would also ensure any crap is blown out and not into the air lines ??? Just a thought ???
-
Good thought, I'll do that. Well it seems I'll have a day more ocupied with omega....not wrong, I like it (wife doesn't) ;D

(http://s3d4.turboimagehost.com/t/8235590_IMAG0494.jpg) (http://www.turboimagehost.com/p/8235590/IMAG0494.jpg.html) Is this the compressor and does the plug you see fut in?
-
Sorry, does it FIT in....mistake :)

-
I think your first picture is of your seconday air injection pump :-/ No idea on your second.
My self levelling compressor is on MY driver's side of the car, under the corner of the bumper & wing.
HTH :y
-
Must say the 2nd picture does look more like a s/l pump,especially as its mounting points are clear in my mind at the moment as replaced mine a week or so ago.
Electrical plug also looks very similar so my money is on picture #2 being the pump.
Picture #1 looks more like the secondary air pump also.
-
Those were only two "things" in the corners of bumper and wings on both sides. I'll take another look as soon as I get back home. In 30 min, I wish i would what does it look like.

2nd pic is from under the right side, under the light.
-
Fast one, please.....Fuse for avto leveling is nuber 27 fuse? Because I'm missing it.... Which fuse is it, 10A 20A? I want to try it, please
-
20A
-
And one more thing, the switch by differencial - I hope previous owner has put it back in right position. I don't want an offroad omega :D
-
Thanks, I'll put fuse in and start the car.......(to be continued)
-
Nothing.....what weight should be in the back? Or maybe it's dead
-
Can you hear the pump start running after the ignition is switched on ?
Simplest method is to pull off 1 of the thin black air lines from the top of the rear suspension shock absorber,then turn ignition on and you should be greated with a steady flow of air from the end of the pipe.
-
Can't do that now because it's raining again. I didn't hear compressor so I'll try this option
-
(http://i1103.photobucket.com/albums/g480/danzigfan1/IMAG0586.jpg) so the compressor is out, now just to see if it gets signal at all or the problem is somewhete else. Sugestions are welcome, thanks
-
Eeemmm, is image too big? First time with photobucket sory
-
Got electricity, still nothing. Going to disassemble compressor now and see what's inside
-

-
IT'S ALIVE......ALIVE!!!!!!!! ;D 8-) :y
-
:y
What had been rubbing on there?
-
Rubbing with effect :D :y
-
Good job! :) Really must look into mine - the pump runs (I believe) as it keeps jacking the back of the car up and not letting it back down again .. ;D
-
No problem, stop to have some tea/coffee when driving by my house and we"ll check it...... ;D :D :D :D :D
