Yet another air suspension tale
I have had intermittent issue with my air suspension. I started with a busted compressor & front valve block that was not functioning properly. Both replaced.
I noticed my car was riding crooked. The LR is up high, en RF is low. Calibrating the suspension using the IID Tool did not change things, so I suspect the height sensors are knackered. This is supported by the fact that the suspension stays up overnight when I pull the EAS fuse, more or less ruling out air strut failures.
I have ordered height sensors and will keep you posted. Any alternative diagnosis I should keep in mind?

Use the Iid tool and check live values of each sensor.It can when others can't,
It will when others won't,
It goes where others don't.

See below for all the values on my car. No matter what I do calibration wise, not much change happening on FR & LR measured heights.

Got around to installing the new height sensors; they were quite challenging to get off and had to enlist some 3rd party help...
The new sensor did the trick on the front end, however the rear left side is still "up in the air". The suspected culprit is now the rear valve block. Will get it sorted in the near future.2015 Discovery 4 SDV6 HSE - Montalicino Red
