Based on google search results, most likely it's either leaking air, or the pump is not filling the tank.
The other error "U0421-68 (2F) = Invalid data received from ride level control module"

Hi did you change Hitachi like for like or was an amk fitted
Hi there, no it was like for like.
Hi, the rears went up ok, the fronts initially rose, then after 20 miles went down and refused to rise. I changed the front valve block as I thought that may have been the culprit. I done a soapy water test but cannot see any visible air leaks.
Thanks Datatek, Icarsoft does tell what the codes mean, I'll have to investigate further.
Looks like it's time to get the soap spray out. That DTC is for air supply fault, i.e. a leak. The fact the rear is raising indicates the compressor & lines to the front & rear valve blocks are OK, it maybe a leaking airbag or pipe from the front valve block.
Thank you all for your help, it was a case of looking for what I called a phantom air leak. So I went back to basics and check the voss fittings on the front air springs, the split olive on the off side wasn't sitting on the airline properly, refitted a new olive and the air leak is cured. I am now in the process of fitting new height sensors front and rear. The soap test didn't show up an airleak. I have invested in a GapIID tool now.
