Well, I replaced the compressor yesterday. I still have the original and a re-build kit for it which I will do at a later time. I see no harm in having a back-up. Here is my issue, the left rear expels a burst or puff of air, then I get the "Suspension Fault Normal Height Only" fault. I have checked and rechecked all the lines and cant seem to find an issue. The suspension seems to air up just fine but over night it drops an inch or two, mainly the left side. Not sure what the problem is but any help would be appreciated.
