Hi can anyone help me the eas works ok when I switch off the engine it starts to lower when I open the door it stops I've noticed it stays up when I open the door wait a few mins for a click then close the door it stays up what's going on

Depends how much it's lowering and where you are parked. If the ground is uneven the car will continue to try to level itself after you stop, it will go down but it should not go down to the bump stops. Opening the door freezes the suspension and stops the self leveling. If it stays up with the door open, it suggests that it is not a leak.
I think you should get the fault codes read, It might be a dodgy height sensor.

Oh and welcome.

Sounds to me like its just leveling itself out. If you are in it solo, when you get out, the drivers side will lift a little as the air pressure is too high for the now reduced weight. as soon as you shut the door the suspension will level itself out - as long as it isn't falling to the stops its probably doing what it should - I wouldn't worry sounds normal.

does sound normal, mine has been doing that since i bought it.
