Have you drained the moisture out of the air system lately? Perhaps a small dose of air brake antifreeze may help as well. Is this a system where you have an electrical sensor dump the air?
-
I drain the tanks daily i have a manual switch where would I add the antifreeze on the tractor i know where for the trailer
-
Put the antifreeze anywhere in the system past the air dryer, I had a Pete 379 were the air dryer wasn't working and the water all seemed to end up in the air suspension feed line. Try draining all the air out of the air tanks and use a funnel to get the antifreeze into each air tank

Ok thanks i will try that
