Air Suspension?
I have a 2012 CLS and once in awhile when I park, I'd hear a short burst of air from the air shocks . Also sometimes, not often when I park the back wheel is low, but as soon as I start it, it rises to the right height. It drives really well with little under 48, 000 miles. I don't drive it a lot but when I do its usually about less than 50 miles a week. Should this be a concern and if so, how much for parts and labor. BTW, I wont go to a dealership, I have a mechanic who has a body shop that strictly works on Mercedes. I was gonna ask him but I thought I'd get the heads up first from you guys first.
