  1. Sorry for such a crappy First post. 2010 Pan Turbo 48,000 miles. I can still hear the compressor going but the vehicle will not go up nor down. The ride height was still good until we attempted to roll it on board ramps to get the car on a lift (was in Sport plus ride height when failed). Once we brought it off the lift on to the board ramp after visual inspection of all lines under the car the suspension is now tucked in on the rear with Low Vehicle warning. I’m told the compressor fails at these -15° temps we had when it happened but like I said I can still hear the pump going and attempting to raise. I don’t nor did I ever hear a hissing sound. Is there a way to put air into the system in order to drive it to my Indy shop. I replaced the relay but that did not fix anything I don’t know if I should replace the Compressor or the valve block. I’m an aircraft mechanic so doing the work myself isn’t an issue since I’m not under warranty anymore BUT how do I know which one has failed the valve block or the compressor? . Never had an issue until this extreme cold weather. Code currently on my Snap-on computer is U0418 (Fault, PSM control unit) and I once had a U0447 (check gateway control unit fault memory content) a while back but when it was reset that U0447 never came back. I’ve looked for answers on other forums but couldn’t get the warm and fuzzy to buy the compressor since mine is actually still pumping. If I keep the battery connected the compressor will continue pumping (shutting off the compressor 5 minutes or so at a time) until the car battery completely dies. Need help.. Tried to post image but limited to 2MB sorry
