I tried searching and couldn't find anything on the forums, but my new to me 03 MM has developed an air suspension issue. The rear is lower than normal, no obvious signs of an air leak. The car has sat overnight and the rear has not changed positions. I had the car on jack stands for about a week with the rear end unsupported. After placing back on the ground and turning the air ride switch back to the on position, the compressor runs for 45-60 seconds but the rear never rises. Using Forscan, I ran the self check and pulled codes C1726 and C1964. All I can find for C1726 is a possible air leak or bad compressor. C1964 is basically stating the compressor has cycled too much which makes sense. The car has 100101 miles on it. Has anyone had a similar issue?
