P38A EAS fault that I am unable to diagnose with certainty

Ok, original fault is back. As before intermittent.

However, since reconditioning the compressor it is working better and now it is clear the front raises and lowers intermittently. I noticed it when stationary and at idle. Didn't throw up a fault at this time though, fault only comes up within about a minute after ignition and perhaps only 1/10 times

Soooo, can this be driver pack related or a faulty sensor? I have a replacement driver pack but not convinced it is new.
Remove the exhaust from the eas block.
The compressor will run, the car will lift a tiny bit. Then the compressor will shut off and the car will lower... If it does this, it's a sensor for sure.

I despair. Seemed OK, then lifted it and raised it a couple of times and then not sure. Compressor ran for ages, danced a bit, then stopped and seemed OK again. Not really sure I know what I am looking at :(.

Have you got a good driver pack you can use to test?
 
The tank is mounted on the chassis under the driver seat and the pipe runs from the valve block down above the passenger chassis rail across the rear cross member and back towards the front, but do the valve block first as if that is letting the stored air out that will be the leak
 
The black plastic thingy is probably the air drier that dries air on the way in and then is cleared by the exhaust air going through it
