Airmatic Malfunction Light, Code C156C00, Car Raises Up
Seeing if any of you would know what this could be. I have a 2010 E550 sedan, non 4K a tic. I had this come on before, airline leaking basically a few months ago. My compressor would not turn on at all so that was the fix after replacing the pump.
A few days ago the light turned on again, so I pulled over to inspect. Noticed that my rear left side was raised up. Same code as when my compressor failed. All other corners were normal height except for the rear left. Once I cleared the code, I hear the valve release some air and then it leveled to normal. After driving a few minutes, the light came on again and the rear left was risen. I just replaced the ride height sensor thinking that was the issue, but then it’s still doing the same thing. Any ideas or has anyone had the same experience? I would think if there’s a bad leak then it would lower and not raise.
