I was driving down the road the other day and my 2007 SL550 it started going into rodeo mode and going up and down independently in each corner in a circular motion. Has anyone ever experienced this before? What was the fix? I hooked my scanner and noticed that the voltage usage on three of the shocks was constantly going up and down in unison, while one was constant. It seemed odd. I drove it again after that and it was moving all over the place.

Do you think it's a bad suspension module or bad shock level sensor?
