2005 air compressor upgraded, won't descent

I had my compressor upgraded to the newer version all installed correctly and had to go to the dealer for the new software update, but when I try to descend to 'Access mode', it errors and goes into 'Extended Mode' and won't go back down. Only after switching the engine off and on again (IT solution ) it goes to normal height

Is there any experts I can take it to, to get it sorted? It's annoying since I spent so much on getting the compressor fixed, it doesn't actually work!! RRS HSE TDV6 Autobiography

Look at the 4x4 display screen, is one of the dots above the wheels flashing?
Could just need calibrating or a new sensor. Bodsys Brake Bible

Dropped it off at the local LR specialist and apparently the release valve is faulty. Not releasing air. Is the valve fixable? Quick look on Disco3 mentions something about greasing the valve up?
Anyone had anything similar? Bit annoying that it could potentially mean a whole new compressor! PLUS fitting. RRS HSE TDV6 Autobiography

More often than not, this is a calibration issue, instead of a faulty compressor.

In fact, in all my days, I have only ever seen 1 single faulty AMK, but hundreds of poor calibrations

Well it was in to do the calibration and they did attempt it but apparently the valve won't release RRS HSE TDV6 Autobiography

Is the compressor valve a separate part? I keep reading about this 'Transfer relief valve' - looks a lot cheaper than a full compressor cost RRS HSE TDV6 Autobiography

Quick update: it's an error in the 'venting gallery' if that helps? Is that an issue known with these AMK ones? RRS HSE TDV6 Autobiography

That's the issue I had with mine, but the suspension wouldn't work at all until the air gallery was empty, then the compressor would kick in
