    EAS inlet valve open

    Hi, can any one help point me in the right direction to help find this fault. I have replace airbags, rebuilt valve block and suspension maintains ride high for several days when parked and works fine in all height modes but I am getting a recurring fault "inlet valve stuck open" at least once a week sometime twice in a day. It always unlocks OK using SW software and things are back to normal. It nearly always happens when I am turning the ignition on after refueling or calling at a shop and has only once faulted while I was driving. Can anybody help I thought the next step might be to change the control pack under the valve block. Cheers Phil

    probably just a sticky solenoid or an o-ring not seated properly... you may not even need to remove the valve block from the car to check and clean. It is the second solenoid from the front on top of the valve block.

    Cheers, Paul.

    it sounds like a driver box fault (the control pack under the valve block).
    the part number is ANR3900.

    Thanks Paul I can always rely on you. Now I know which solenoid it is I will clean and replace o rings and see if that fixes it.

    Thanks Rupert I will try Paul's suggestion first as it sounds like I can do it without removing the valve block. If it doesn't solve it I will see if I can borrow a driver to try before I purchase a new one. Experience tells me that an intermittent fault like this can be any number of things. Cheers Phil

    PS If anyone reading this thread has a good EAS driver box I could use to fault test this issue it would be much appreciated.

    I, too, suspect the valve driver pack.

    Hi Paul many thanks for help. I cleaned and checked the inlet solenoid last night there were no obvious signs of a problem. I will see how we go the next few days and if it faults again I will change the driver at the weekend. Thanks again for your help. Cheers Phil

    I'm with Rupert. I Had a simular problem. Also Exhaust value perminately Closed / Open. Did all the usual "o" rings etc then Fitted new drive motor. All Fixed, for now that is . Got mine from LR Direct in the U.K. Cheapest I could find at the time. From memory delivery was about a week. I'm happy

    Best of luck with your problem.
