Inactive air susp l322

My 53 plate l322 diesel has started to display a fault on its display after about 30 miles that says air susp inactive and hdc inactive if you stop turn off ignition and back on again its gone but comes back later there are some other warning lights that come on at the same time that all go out when restarted diagnostics has found no fault any ideas what it could be?

Compressor overheating due to leaks or weak compressor maybe?

if you have you own diagnostics, see if you can check it before you turn off the car and resetting the fault. If that's possible?

Thanks for the replies I don't have my own diagnostics but my local garage will help me out I just have to drive it far enough to get it to come on but I was wondering if driving with the fault would cause damage

unless something major has occurred, normally it's just deactivated so nothing else can come of it. But, please dont hold me to that...
