Ok, I’m now at a point where I have diagnosed with RSW and the faults are
1 front left valve fault
14 front valves supply fault
2 front right valve fault
I’ve tried a front cross link from a breaker but still the same. Codes just won’t clear.

what could be the problem?

I can manually bridge the pins on the ECU plus and open the valves/pump up the suspension.
 
I’m still chasing this fault if anyone has any suggestions?

Are the main suspension valve blocks a common fault?
 
An air supply fault canake the computer think it's having a valve issue if the car doesn't rise when demanded to do so?

Have all hard faults been cleared ?

when I clear them using All comms, the lights come up on dash for a second and go off. Faults are still there. Ive tonight tried a different main valve block to no effect. When it says supply, is it talking about voltage or air?
 
That’s sounds like it could be an internal logarithm that sees it not doing what it should (assuming compresser is good and filling tank)
So it’s not moving quick enough?
My wild guess:)
Leak
Valves blocked with broken down desiccant
Suspension stiff cos of knackered bushes.

The light on the dash comes on and goes off so quick it doesn’t have time to move,

3 years I’ve been fighting it to get it working
 
Does the compressor run?
I need to read back see what you have done:rolleyes: but not tonight on the phone:)

Yes, compressor runs when ignition switched on.
I can also manually bridge the pins on the EAS ECU multi plugs and pump up each corner using the compressor
 
So when you bypass the ecu it doesn’t see what’s “expected”
So if you get it up then start again it shoud think everything is ok?
Will it actually stay up overnight?

The car is currently pumped up, it goes down drivers side a few cm over about a week of not being used.

I tried clearing codes when it was level and still no luck.
 
Right. Plugged in all comms this morning.

was havoc trying to read modules. Kept saying ECU offline, then it would say k bus offline! Had to open comms a lot of times to try and read the modules.

I can’t see anywhere in all comms to check the pressure in the reservoir?

Sounds like your problem may not be the EAS.

Its the first time its done this, normally it connects fine but EAS still doesnt clear faults.

I think im now at the point where i need to start changing everything as no-one seems to have any ideas what it could be.
