There is a noise coming from the right rear suspension. It sounds like the compressor which is part of the electronics leveling function of the car. It is doing what it is supposed to be doing but is extra loud and very annoying. I need to know is this something that I can repair/replace or a dealer issue. I am hoping that I will be able to do it because of the obvious costs the dealers charge. Is the compressor part of the rear strut? Could it just be something loose? It does go through the normal cycle of kicking in 20 seconds after the exhaust solenoid is activated and levels everything up but again is so loud.
