I do not have the ability to read codes yet, and closest dealer is an hour and a half away, so it was an educated guess.
Edit-
When the vehicle had not been used for over 30 minutes or so, the fault would take around 5 minutes of running to appear, but if starting the car within 30 minutes of turning it off, the fault would take about 5-10 seconds to appear. It seems the suspension ECM "remembered" that it had a fault (and as a guess) to preserve the compressor's life.
