I have the exact same issue (amber light.) Oddly enough, mine started happening the exact same time my amber brake light came on indicating I need new brakes. I am doing pads and rotors in a few days. Any chance that this would trigger the suspension fault? Just for the hell of it, I ordered a new drier and compressor rebuild kit too. My LR3 has 103K on it so it's probably time. No compressor issues until now so I suppose I am lucky!
