P O S self levelling suspension
« on: 28 January 2013, 16:47:57 »

My silver shed - Elite Estate has the useless level system at rear- I dont hear the pump working (were is it located?) and the rear end is up in the air 3-4" + gap from arch to top of wheel so disconnected lever while car running-nothing-is is there a fuse or relay for the chuffing thing or is it best to throw the lot in the scrap bin and fit normal shox :y I cant get back to any replies later as taking mrs to suprise Wedding Anniversary do :y :y

It's not releasing air at the pump, hence it's not responding to the sensor arm.

Pull the air lines off the shock body to release the air for now/if the back gets too high. Then refit them as the bladders will chaif themselves to bits with no air at all in them.

Replace SL pump in the drivers wing behind fog light.


Ps, when/if you remove the airlines be carefull the arch doesn't trap your arm as the car drops. It's quite a slow controlled drop but safety first. Might need a jack to re fit the lines.


And dont be tempted to run it with the relay disconnected as it will destroy the SL shock bladders if driven.

You'll probably find either the relief valve on the pump is blocked or has failed in some way, or the level sensor has failed.

Pump is up under the offside front wing ahead of the wheelarch liner.

Are you looking at the correct sensor?

From memory the levelling sensor is well inboard by the diff, the one just ahead of the nearside rear wheel being for the headlight levelling.

Oh, good. I was thinking about going to  the Isle of Wight. Might be a little old for Glastonbury and I'm not that keen on mud. Beer festivals, of course, are right up my street. :y

It won't be the relay as that just activates the pump but it's located in the panel in the driver's footwell. One of the 2 smaller relays on this panel, the other being for the main beam headlamps. Can't remember which one it is.

I doubt the fuse would cause it to stick high. Most likely cause is failure to release air from the system, as said.

It's not fuse or relay related.
Two small black relays very top left of cabin fuse box. If you pull one, make sure your high beam still works.

pump operates on each start up automatically. It pumps up until the sensor arm tells it to stop, it then releases air(if needed) down to the correct ride height.

If the pump cant release air, it will gradually raise the rear on each start until it looks daft. The damping is really poor if its too high as well, do go steady over bumps in corners, as the suspension will just bounce off bumps with no weight in the boot. Dodgy! Especially in the wet.

Hi All

I have a question - do all omega elites have this air suspension? - ours seems to sit at the right level and rides o.k, but it bottoms out pretty easily.

I could be wrong but I could have sworn I saw regular springs on the back of ours when I washed it, but maybe not.

Tbh, I bloody hope it doesnt have air suspension - the air suspension on our discovery TD5 is the stuff of my nightmares :-(

All Elites (I'm sure of) and some CDX cars (I think) have it - they still have regular springs, the air bladders are in the shock absorber body

oh, right - that explains things then, thanks.

I wonder if ours doesnt pump up much, which is why it bottoms out easily.  I'll have to do some experimenting at the weekend with it.
