Yes, I believe that is the air suspension. I am a newbie here so I won't give to detailed an answer but I think it can be anything from a leaky/blown airbag to a bad compressor. There are people here who say it can be fixed DYI fairly easily and I've seen guys here complain about a $2,200 dealer repair.

I had that fault on my new to me 2012 GL450 and the dealer replaced the front bags and compressor under warranty.

I hope that helps.
