I have a 2019 GLS 450 - I have had it for about 2 years, Purchased with 54k Miles, Currently 94k miles and my problems started at 92k
Driving the car one evening and the Ride just started getting all Bouncy in the Rear.....
When I parked the Vehicle - I googled what the issue may be and it came up as potentially an AirMatic issue. I found a work around to Reset the Airmatic by hoding down the Suspension Lift Button for 45 Seconds and let it Cycle through.
It was good for about a 2 weeks, then the "Malfunction" light came on. I turned Car off and on and it went out for about a week.
Car is NOT leaning, squatting or anything that looks like Air Suspension is not working.
New Years Eve - driving the Car - the Malfunction Light came on again and I tried to cycle through again and then received the "Compressor is Cooling Down" Message.
For the Next few days the malfunction light would come on in different points, maybe 20 mins into driving, then another time driving could be 10 mins.
Today it came on as soon as I turned on the Car...... We live in the mountains, on top of a Mountain, Very Steep road with Switch Backs.
As I was gently going down the mountain on the Snow/Ice Covered Road - I had in M1 to make sure I was not using to much brake but using my engine to maintain the slow speed
As I got halfway down and using a little break - My Dash Lit up like a Christmas Tree
ABS Light
Anti Traction Light
Message that my Assisted Breaking was disabled
When I got to the Bottom - Turned Car off and on and All lights went off - But now I have the check engine light
Went a Few Hundred Feet and Malfunction light for AirMatic came back on.
Any thoughts - on All these things might be connected?

"Compressor is Cooling Down" implies it's been running for a long time, which indicates you have a leak somewhere. I'd start there. It's not necessarily a leak in one of the air bags; it could be leaking from the circuit that lowers the car.

OP hasn't been seen since an hour after he made that post, his one and only.
