L322 EAS problem

Hello, i have a 2004 Range Rover. The EAS is a real nightmare. A while ago the car would not go up. The front height sensors where giving the weirdest mm, like -6745mm. i have replaced both front height sensors and still the weird figures. The front left air balloon is also replaced, definatly had a leak. The only faultcode i get is Canbus fault. If i clear it it returns. Th emayor problem is that when i connect the battery the compressor kicks in works a while the car is not going up or down and a few seconds later i hear the release valve opening letting the air out. Than the compressor kicks in again. Can someone please guide me to what the problem might be. I have manually raised the car but as soon as i connect the EAS ecu the release valve opens and the car gets to its lowest again

What diagnostics are you using?

sorry for not mentioning that, i use launch X431 master

Well I have never heard of that one before - but their website says it covers the Range Rover and the Vehicle List does indicate it will do the EAS system too!!

Do you have any lights on the vehicle height selection switch and ride height indicator??

I have the right light for going up/down blinking and sometimes the left road light is on. This morning i played with it again and filled the system manually. Connected the EAS ecu and in a few seconds all the way down again. compressor kicks in for about 20-30 sec, not going up and after about 10 seconds the release valve opens. I hear 2 opening, one under the rear side of the car and the one near the compressor. I will add some pictures of the data

For an L322 the battery voltage shown looks low.
