putting my 4.6 hse back on air,4new air bags ,2 new ride height sensors, recon compressor replaced / repaired air lines. Using rsw solutions software to recalibrate and got car to go to all the different ride height settings and stored said settings with no faults showing but when I take it off the laptop it doesn't work on the buttons and after about an hour or so after leaving it on max height the back drops to low setting not bump stops and front stays on max ,what am I missing or doing wrong ? Cant find any air leaks on rear and shoudnt it drop all 4 corners if there is a leak? Starting to do my head in now !! any advice would be most welcome
