You said "restored" calibration. Did you actually measure and calibrate? If not, need to do that first.

Are there any stored diagnostic codes. Do you have Topix ? To check for any technical bulletins. For instance the compressor is struggling to exhaust its gasses and you need to modify the outlet?

Make sure you have all the sensors in the right spot. I installed a LR sensor on the RR rear once.

Aly,If you get same message on the second attempt,you can try inputting the measurements within the allowed range,so your left frt is is actually 8mm off, right frt is 7mm,left rear is 6mm,right rear is 7mm​.​They can be higher or lower of the allowed value presently,you need to take precise readings and enter or try to enter it within the range,must get the calibration stage…

hi, are you sure this not just an air leak, possible rear corner valve leaking back to reservoir or similar. try spraying soapy water around, disconnect feed pipe to rear corner valve, then spray soapy water at valve, should not be leaking back ie, holds pressure in rear suspension. regards STEVE CAMPBELL very old range rover mechanic.

There have been some reports of the pressure reservoir leaking due to corrosion. Leak causes pump to run too much eventually burning up. Soapy water again!
