Hi yes it’s the same with both old and new sensors although the old passenger side sensor was seized up so would have been giving inaccurate readings anyway
I’m going to try and find the cone thing tomorrow morning as kds said and check it for blockages
Thanks for your reply

I guess you might have found it by now if not its under compressor cover under spare wheel, just going to throw this out there see what people think how about doing a battery reset, if I remember right the suspension normally jumps to standard height then. Any thoughts @myfirstl322 @Saint.V8 @backinblack @holidaychicken and a few other l322 owners I cant think of right now plus @gold rover of course.

Can't see how it would hurt. Only other thing I can think of is different diagnostics?
 
I'm as in the dark as OP, never had any problems with either my first or second (current SUPERCHARGED ;)),
but to me it sounds valve block also.

Thank you everyone for the replies!!
I’m thinking that the centre valve block may be the problem as I understand the air is not being returned to the tank but instead being forced into the front airbags by either a defective solenoid or crack internally allowing air to pass !?
as I’m skint at the minute I’m going to check eBay and see if I can find a good 2nd hand valve block wish me luck

Get an RSW suspension reset tool off eBay or online. Not expensive and you will use it over the years. Best diagnostic that’s affordable I find is the icar for the Range Rover. It does 90% of what you’ll need. If the arse is going up and down then the compressor is obviously working to a degree and if the fronts not going down while stood that has no leaks. I would suggest slowly releasing some air out of the front each side by the pipe going into the bags. Release slowly though. Get it to where it sits about level and then fire it up and see what happens. It may just be a reset job.
 
Hi I tried that yesterday (letting air off )
Started engine and it went straight back up
So let it off again pressed the button to lock suspension was ok until I drove it got to 20mph and straight back up again

what about letting the air out to where you need to be again, lock the suspension, then recalibrate?

Or did you buy it from a dealer?

If I recalibrate it goes straight back up
No faults when scanned with solus
I bought it private so I’m on my own regarding warranty etc
 
I would think the cross link valve or the the valve body has taken a dump as in got confused. if you can depressurise the complete system and perform a full battery disconnect reset and try again it might help. Try clearing all faults from all systems not just EAS.
The later models did away with the cross link.

Keeping in the back of your mind that very rarely when disconnecting the battery the immobiliser can lose its memory and disable the vehicle...

Valve Block
The five way air suspension valve block is located under the RH sill of the vehicle, and is mounted forward of the air
reservoir. The valve block is held in place on the air reservoir support bracket by 3 studs and secured by nuts. The
studs are bonded into rubber mounts which isolates solenoid operation from the vehicle.
The valve block contains five solenoid operated valves which are controlled by the air suspension ECU. Four of the
valves, known as corner valves, control the air flow to and from air springs, via the cross-link valves. The fifth valve,
known as the reservoir valve, controls the air pressure supply from the reservoir to the air springs, via the corner
valves and cross-link valves and also from the compressor to the reservoir.
Removal of the valve block will require full depressurisation of the air suspension system. The valve block is a nonseviceable
item and should not be disassembled.

The cross-link valves are located at the rear of the front RH wheel arch, behind the liner for the front valve and at the
top of the rear RH wheel arch, behind the liner for the rear valve. The valves are attached to the body by three fixing
and are rubber mounted to isolate solenoid noise.
The cross-link valves comprise a single large solenoid valve with connections to the LH and RH air springs and also
connections for each air spring from the reservoir mounted valve block. The solenoid operated valve is controlled by
the air suspension ECU. When the solenoid is energised, the cross-link valve connects the two air springs together,
allowing air to flow between them if required. This provides additional articulation of the suspension improving the offroad
capabilities of the vehicle and an improvement in low speed ride comfort.
The air suspension ECU senses that the vehicle is off-road by comparing rapid changes in signals from the height
sensors. The operation of the cross-link valves is fully automatic, requiring no driver intervention.
The cross link valves are only operated at vehicle speeds of 12.5 mph (20 km/h) and below. At vehicle speeds above
12.5 mph (20 km/h), the cross link valves remain closed.
 
Couple of other options,
1. Take your wallet out of the boot :)
2. Let some air out of the front bags then take the compressor relay out until you can find the fault.
