Hi all
Hope someone can help I noticed today that my car was very high at the rear it looked just like a wedge on the road. I had took it for its Mot and the lad did say "My that looks a bit high at the Rear" I had not noticed it before but when i was coming home from my daughter the other evening i  i thought the car was not running with its usual straight leveled feeling. It cant be the pump as its pumped right up i asked the garage but he just looked into my face and curled his lip obviosly not a clue . I wondered if it was the rear sensor but its not moving at all, and the car as not gone down yet 4hrs after i parked up.
I hope someone can tell me  whats wrong and if its going to be expensive Knowing my luck ide say it is

Thanks in anticipation
Robert

There is a sensor Bob on the drivers side of the rear axle, you can lower it or lift the car with that. You need to take it off the rubber and see what happens then adjust accordingly

Thanks for that daz ill see bloke at local garage

Pull the air line off one of the shocks to let it down again. Either sensor not reading correctly, or the pump is not releasing air. The self level pump runs for a short time on start up usually, pumps up, sees the required ride hight as correct, then let's air out if needed.

If cant let the air out, it just keeps pumping up over time and the back keeps rising.

Or the sensor is reading incorrectly.

See maintenance guide for test self level suspension.

thanks chris
just measured it before start up as it been stood all weekend and it is
 from ground to wheel arch
Ds= 710
Ns= 720
 im going into town shortly and letting garage look at the back sensor ill measure it when i start it up see if it changes i suppose it will

It will only pump up if it thinks its low. So if its high, and you hear the pump, thats likely to be sensor fault.

If its just always high, and you never hear pump, it could be the pump cannot release air, or something else amiss (eg, wrong springs or shocks)

I had the springs changed at the same garage  last year as he said one was broke so i told him to change both i did emphasise that it was self levelling they said "yes sir we know" the springs were KYB but in all honesty i had not noticed if it indeed it was high when they  changed them it was when the car was parked waiting and i was a few feet away that i noticed it looked high. but i know its different as the view out of the rear view mirror is different now i yhink about it and thats on the memory position.  By the way what is the measurement for the rear suspension
TIA

Thanks for all yr help with this, garage is looking at it on thursday
does anyone know the measurement from floor to wheel arch mine is
740mm its just i would like to be armed with the correct figure, i could not find it in hand book

Thanks all

[albitz]

740 is very high indeed imo.Essex Bigal did some measuring a while back,and istr elite saloon from floor to wheelarch was around 675.
Quite a few elites seem to be fitted with LA coded springs which makes them sit a little high apparently,but Im sure its nowhere near 740.

[aaronjb]

There's some measurements in this thread: http://www.omegaowners.com/forum/index.php?topic=84324

As Albs says, somewhere around 650-675 'at rest' seems to be about right. I'd measure mine, but I'm pretty sure it has the same problem 

[albitz]

Another link to confirm the same thing - around 675mm is the correct height. I think that 740 is waaay to high. Either the wrong springs have been fitted,or they have done something badly wrong when reassembling.

I had numerous issues with mine tyring to get the correct ride height sorted.

In the end I replaced the pump and the rear axle sensor from a breaker.Problem was resolved,but am convinced it was a fault with the original pump.It never seemd to drop back ,like yours just kept pushing more air in.Somewhee in the pump system is a releasse valve and sure that was the fault with mine.

Worth picking up a replacement pump from a breaker ..around £25/£30 expect and changing it over.Will be a lot less than the labour rate you could pay at a garage for them to experiment at your cost.

By the way mine sits totally stable at 660mm from ground to underside of rear arch and thats with brand new GM self leveling shocks and KYB s/l springs

[albitz]

Reading back from the start of the thread, it could be more than one problem ? Car sat high after new springs were fitted,now sitting very high and staying there al the time,if Im reading it correctly ?
Imo needs someone to look at it who knows what they are looking at.Any knowledgeable OOFers nearby ?

Hi all
First thank you for all your help on this matter it truly helped
Garage man checked the sensor in as much moving lever when he shoved the lever up it rose further but would not come down when he pulled lever down. He then took off pipe and there was loads of pressure and suspension dropped to 670 height . the pump then started back and pumped it only slightly but  did not drop anymore. He seems to think that it is this sensor that is causing the bother so as said soon as i get a replacement he will fit it if that does not work  he will have to look further. he charged me a fiver so couldnt complain there.

Thanks again
