    Definitely sounds like something stuck closed in valve block then.. double check NRV valves for scoring on needles. sounding like it wont allow air to release to drop height another check may be exhaust valve.
    Good luck.

    I put new O rings on the NR valves, but the metal triangle tips are scored, or worn, I dont see how this could affect their function

Does anyone know what possible causes for this are?

    Going to wade height is usually a sign of a bad driver pack , go through all the other checks first and if it keeps happening often i would change driver pack .

    EAS Fixed Solution explained

    Hey guys my car is currently running 100% and the software is running well also. The problem was as follows. When I first rebuilt the valve block I put a NRV backwards (not sure which one but both front springs on bump stops). While I was sorting out those issues I kept the EAS components in the car separate and not in the EAS box to allow quicker access to components. One last error I made was to analyse all the plugs and incorrectly concluded that land rover had made them all individually keyed. This lead me to fix the EAS except for the fact that the driver pack plugs were switched, the in from CPU was plugged to the solenoids and vice versa. This is the best type of problem as its the easiest to solve and I now have a perfect Pegasus
