Bought the car last August, no air suspension leaks until March, where the front end would be completely slammed after sitting ~8 hours. This happened for about 4 days straight, then fixed itself, then happened a couple weeks later twice in a row. Every time I was parked on a slight downhill. Since then, the air suspension has been fine. Even left it parking for ~80 hours on a slight downhill and the compressor ran for about 15 seconds after starting and that was it. I've never had the compressor come on while driving, except for when slowing below freeway speeds.
Any suggestions? Is it possible a purge valve stuck open?
