Car sitting high releases air after I park
Hi everyone,
I'm new on here and new to the Mercedes world. Had Audi my entire life, but my dream car was the CLS63 S. I have 56K miles with some concerns. I have warranty on the car which I'm glad I got. The car rear is sitting really high and doesn't go down even when I'm driving fast on the fwy or when on S and S+. But, when I park the car it starts to release air and drop. Do you think there is a problem with the AIRMATIC suspension?
2nd concern, my friend did an oil and said there is an oil leak with caked on oil the bottom panel. There was also fresh oil leaking but very minor. I'm waiting for warranty to kick in 30 days/1k miles for me to take to dealer.
Also, the steering wheel sounds like there is something loose and rolling around inside as I turn it. I don't know if it could be a wire as all the buttons work. I've been told it could be a long wire hitting on something but it sounds like a loose screw inside rolling around as I turn it. Anyone have any of these issues and insight you can give me?
Thanks MB FAM.

How intense is the drop when parked? When I had a W219 CLS, one of my struts was leaking and would be fine when driving, but would lose all air when parked. At certain angles, the car will want to lower itself more than others. It shouldn't be very intense though.
I assume you're talking about the skid plate under the engine, meaning anything above that could be leaking and dripping down. I think getting it inspected is the easiest way to diagnose this.
Hard to diagnose the steering wheel noise. If it's something that's moving freely with the wheel while you turn it I'd think its some screw, nut, washer, or any other little piece that fell out and is rolling around inside. I would first try to feel around to see if any pieces on the wheel are loose. If the noise is 100% inside of the steering wheel then you'd have to disassemble it.
