P38 Air suspension issues

Hi can anyone give a diagnosis from following info. When I bought Rangie one airbag had blown so didn't go up. Replaced all four airbags and goes up and down now. When I leave it overnight it goes down to low level.

Also if I start it up and adjust the suspension on the dash without driving anywhere it goes up and down but the front doesn't go up as a pair it seems to go up and down on individual corners at a time a big like a fairground ride

Rear should rise first, then front, then rear, then front to level. When you did suspension did you play with valve block. If you did make sure solenoid valve coils are in correct position. They MUST go back where they came from.

no all i did was open tailgate and do one corner, then lower car start it up check for rise and fall and then same again.
when i turn engine off after a few minutes the car lowers itself down is this normal procedure, or is it meant to stay up

It relevels once to the lowest corner reading.....then once every 6 hours....if yours is going all the way down when you close the door....either a height sensor is reading incorrectly making the ECU think that that corner is lower than the rest (hence the car is trying to lower the rest of the car to match that corner) or there is a leak

When you replaced the airbags, you will have jacked the car up, the sensors on each corner will have moved further than normal, although still within limits, but may have picked up crap so giving false readings.
You need it on diagnostics.
