After the big suspension marathon yesterday we discovered the S/L wasn't working

Anyway... Changed compressor over today and it's firing up briefly. Now got a sensor code. I assume the only one is the one on the rear axle?

I'll change that tomorrow but here's the thing... I powered up the compressor manually and the suspension didn't seem to rise

Other question... Where does the rubber pipe that connects to the pump unit twice and goes up towards the headlamp go and what does it do?

Is the newly fitted pump known to be good?


I suppose now he's cleared off we can't ask the previous owner either.

[chrisgixer]

Only one sensor afaik btw.

Are the air lines to shocks secure, they seemed ok when I fitted them but it was a long day. Any hissing?
If its calling for air but not rising would that throw a sensor fault? Air leak for example?

[05omegav6]

A couple of daft questions...or three
1. is the sensor plugged in?
2. it is the sensor inboard of the drivers side rear wheel?
3. have you checked the fuse/relay under the steering column?

Yes

Ps check the integrity of the loom by the plug to sensor. It might of got trapped or something daft, given the work done. I did notice the plug wasn't clipped up properly.

Going over to the unit again shortly to check/swap the sensor from the other car.

Pump is known to be good, and no hissing... All air lines seem to be intact. I will check the sensor wiring later. Strange thing is even running pump manually it doesn't seem to be raiding suspension but I wonder if it is venting automatically because of the sensor fault 

[tunnie]

Is it worth releasing the feed pipe to each shock? As that would confirm air pressure is there, would also allow the suspension to lower. Easier to see it rise if you manually activate the pump again?

[Lazydocker]

Shocks are brand spankers and don't seem to be taking air so I am assuming it's venting.

The thicker rubber tubbing on the compressor is prone to going brittle and splitting.

Worth checking its sound..I ended up replumbing the bits of pump piework with new rubber fuel line to ensure all air tight.Pump should product good flow of air with the shocks feed pipe disconnected if its working ok..then just a matter of checking all the thin pipes and joints at rear .

1 section of pipework from pump clips up above head light and is the open vent pipe.Other bits are valve to pump and are connected

my 3.0 elite has self leveling but have never noticed it in action, also when I tow the racing car it goes down at the rear pretty much the same as my previous non SL Omega would do when towing.

Its had recent new s/l shocks from Vaux in 2011 maybe its not functioning? How can you tell when the SL suspension is working?

[albitz]

Just after switching on the ignition you should hear the S/L pump starting up.Its a small compressor situated behind the o/s front wing if you want to have a listen.
Visible here with the wing removed.



If that's working the other likely potential problem areas are an airleak between pump and shocks,level sensor not working,or problems with the shocks themselves.

That's not right, there's a problem somewhere.

There is a guide in maintenance re tesingt self levelling.

It should maintain the ride height at all times.

thanks for the replies will need to check it out and see

[albitz]

If the pump isn't working start with the simple stuff like fuses,connectors etc.and then delve further.
