Hey all. So below are the measurements taken today on my drive which in fairness isn't completely flat. Measurements taken as the car leans low on the passenger side front and as such is higher in the driver side rear. So took measurements in normal height having left it over night, then in off road mode. I've now pulled the fuse and will measure again tomorrow to see what I've lost. Did the old soap and water and couldn't really see any leaks in the bags, the valve block seems OK and the compressor although kicking in every other morning for a minute or so, isn't too noisy and the vehicle is raising and lowering as it should just not staying level. I suspect calibration is out more than anything but cannot find a decent place that is flat enough to do a calibration with the tool.

What I understand the values should be
Front 461
Rear 465

What I measure in each setting

Normal height ON DRIVE

PF 437 (-24)
PR 466 (+1)
DF 486 (+25)
DR 502 (+37)

OFF ROAD

PF 510 (+73)
PR 530 (+64)
DF 533 (+47)
DR 548 (+46)

Thoughts?

No warning lights doesn't seem to get any worse if left for days , I.e stays at the lower height but doesn't seem to drop any lower.
