Today I was setting up to do the rear brake pads. To do so it says to raise the truck via the suspension button on the center dash. I did that and everything seemed fine and then all of a sudden I heard a loud PSSHHHHH! Like a truck with air brakes just pulled up.

obviously something went wrong. Weird part, no codes, check engine light etc. it is sitting weird, particular low at passenger rear and high on driver front. I drove it hoping it would settle but didn’t. Also when driving it didn’t seem like a corner lost an airbag.

As I was fiddling with the suspension raise button I would get a message on the dash that said “compressor cooling”. I suppose that’s the air compressor for the suspension. Is that the problem?

Sounds like you lost the passenger / rear air bag. Do a search on this forum for the preferred replacement parts if you're DIY. There seem to be two brands that most like: Corteco and Arnott. Some have said that the Corteco brand is Mercedes' OE

That's probably from trying to inflate a bag with a hole in it...

Yes and I would be careful about the compressor going caput too.
