On my X75D, my SAS does allow to adjust to the various heights. However, the onscreen indicator always moves back to Standard, even if it's in very low or very high. I can feel the car move up or down and it stays in that position...it's just not accurately reflect on the screen. At pickup last Thursday, the Delivery Experience guys said the car just needed some calibrating...but I've driven 150 miles already and SAS won't accurately reflect the correct height. Any suggestions?
