Hi Sean

You either have a leak in the air system or the ride height sensor is faulty.

You could try to diagnose a leak by listening for escaping air whilst the air compressor is running.

Failing that it will need to go to a garage - preferably one with air suspension experience

Hope you get it sorted soon

Also check that the arm from a height sensor isn't broken because they do break.  This is from a different vehicle but the long arm or rod at the end is similar.  Is it down on one side or both?

Another way is to brush soapy liquid on joints or even the whole length of the pipes themselves - where it bubbles, there it leaks
