Hey guys, I put this in another thread about 3-4 mgs ago to keep from starting a new 1, but never got an answer.
Late last yr, I was getting the "Normal height fault only" error, so after searching here, I saw that the drier could be the issue.
So, I bought a drier & relay (didn't get the valve) & after getting the drier & relay installed, the fault went away, but @the same time, I started hearing the burst of air @start up & sometimes after shutting the truck off, this of course was due to the truck self leveling etc.
Well eventually, after getting my rims refurbished, which left the truck jacked up a few days with no rims or tires, the fault came back & of course I still hear the air.
Now, the levelling works as it should, but kicks off after about a min or so & I get the fault, along with hearing the air. I think I'm more concerned with that part of it honestly, because I can't find much on the air burst noise...
