I recently had to replace the compressor, valve block, manifold and two air lines on my 2016 Bighorn EcoDiesel. They didn't replace any of the sensors or air bags. Very costly repair at the dealer. The system seems to work ok now but the driver front is around 3/4 of an inch lower than the passenger side. I figured it would level itself out after a few days but there is still a difference. I tried re-setting it by pulling the fuse, holding both button down but it's still not level. The dealer is a fair distance away and I'd hate to have to bring it back to them if there is a simple fix.
