Bob,
Good luck with the troubleshooting. I unfortunately am also having intermittent issues with my 2004 and the dreaded "air suspension inactive" message.
I believe that my problem relates to having moisture in the system, as my problem will only rear it's ugly head when I park my Rover outside in sub-zero weather. I bought a product called EAS Activate which will clear the "inactive message" and also provide some rudimenatry info as to what might be the cause of your problems. Short of the EAS activate, you will need to take your rover to the dealer to get the system active again and they may/may not be able to provide a definitive diagnosis.
Seems that there have been a number of fixes reported including a software update, replacing the valve block/compressor, and the various sensors.
