StuartT, so you are saying that this coach has air leveling only?
Our '08 Dynasty (just sold) had air and hydraulics. The air clicks like you describe but ours seemed to find the level pretty quick. The pad will go into a 'holding' mode to monitor the leveling and will re-level if needed. The green light should have a slow blink, not rapid, once finished.
When starting the motorhome, when you turn the key just before you engage the starter, there is a clicking sound that goes down underneath the whole coach. I asked about that clicking but apparently it is normal. I just waited until it stopped then I started the coach.
If I started the coach before the clicking stopped, it continued it's regular clicking cycle. So, this clicking at starting may not be what you are talking about but I wanted to point it out.
Also, don't walk around the coach while it is leveling as it tries to compensate for the additional movement.
Good luck,
MM.
