When mine developed a tilt and the readings were out by a mile on the NSF sensor, it was a corroded connector. Worth checking the connector at the EAS ECU under the passenger seat. I see no need to deflate the bags, just leave a door open to freeze the system, a couple of axle stands so it can't squash you, remove the connectors and measure the resistance on both front sensors with a DVM, they should be similar to within a few ohms if the car is level. You can then put the connectors back and do the same resistance check at the ECU connector which will verify the wiring.
Small up date, even with the sensor on the near side front "calibrated" to sit 20 POINTS lower than the offside it still does not sit level, it still attemps to make the nearside higher, when the truck is stationary and engine running the suspension keeps trying to adjust the front to level it , you can hear solenoids and pump working every 30 seconds or so ,
I'm gonna measure the resistance at the sensors but something is still not right , I still have the nearside sensor going 20 points below the lowest setting when the truck is in access mode , 3 sensors read to within a couple of points of 65 but the nearside is reading 45 or there abouts , in theory this "live figure" is lower than sitting on the bump stops !

Seem to be getting some where with this, removed both front sensors, measured resistance at 3 points , top center bottom, established that the off side front sensor was reading incorrect , at certain points, replaced it and plugged unlock software in, now when bags are deflated and truck is on level ground both sensors read equal 
now my "20 point " difference can be corrected and both sensors reset/ recalibrated
The problem is now 95% resolved, now establishing that a sensor was the " main" problem I have established the problem is with off side, even now a mother sensor is fitted the osf still sits slightly lower than nearside even with different figures set on software, I now think there is a slight leak to the OSf bag, I have sprayed it with soapy water and no bubbles but I think possible if it does have a leak it may be out of sight from underneath, also what points me to a leak is that ever minute or so with the vehicle staitionary the pump kick s in for a few seconds, the vehicle doesn't sink or raise tho ( noticeably )

You will never get the EAS to sit absolutely the same at each corner. When Landrover do the set up they try to get the sensors to read within two beats side to side. BUT the tolerance is within plus or minus 7mm of the standard setting either side, with a two beat difference. If you try and set it absolutely the same side to side you will have a larger difference than two beats. It is highly unlikely you will set say 150 on both fronts and them be the same height, arch to wheel centre. There will always be a difference either in number of beats or height readings side to side.
I'm not going for perfect , but you can see the difference looking over the bonnet and you can feel it when driving round corners, it feels like it rolls more when you turn in towards the lower corner, gonna fit a new bag as I'm sure it has a leak , just one that I can't get to
