air suspension malfunction...sometimes
I have a 2014 GL450. Yesterday I received an air suspension malfunction error when driving on the interstate. I got home and tried lifting with the button. The dash showed it was lifting and the red button light was flashing, but there was no lift. I did some sleuthing last night and figured I need a new air compressor. Easy enough.
I went out today and noticed there was no sagging at any corner that I could see. I used the button and was able to raise and lower it several times. I ran some errands for about an hour and the error popped up again while sitting in the pharmacy drive thru. This evening, I had my son press the button while I held my ear near the compressor area. It seemed to work. The car went up and down two or three times without any issues. I have not gotten the error others have posted about the compressor needing to cool down.
I have a new compressor on the way, but I wondering if it might be something else. What do you think? Any ideas?

Hi i need help,
I got 2013 GL 450 4 MATIC 99500 miles on it, sometimes rear passenger side sag after parking couple hours, while unlocking car sometimes hearing air pressure noise and it rise by itself. There is no lights on dashboard no warning sign such as Mulfunctioning. Also risining and lowering works good. What is this issue? It sign that it need to be replaced or what? Thanks
P.S overnight parking it doesnot sag

There won't be a warning on the dashboard unless the leak is sever enough to cause malfunction. From what you are describing, it sounds like a typical air bag leak. I had this happen with one of the rear bags, bought two from Arnott and replaced myself. Very easy job - remove the 40A large orange fuse from the fuse bank in the engine bay to disable the suspension, take the wheel off, disconnect the air line fitting and pop the airbag out from the plastic connector on the upper suspension arm. The bag then comes out.

It's the large orange 40 amp fuse in the fuse box in the engine bay. Don't remember whether or not it is marked 40S.
You don't need a lift, a jack is fine. When you take the fuse out the air suspension doesn't sag - it just stays inactive. Once you take off the air line fitting from the bag you are replacing, this bag will release air and you'll be able to take it out. The rest of the bags stay inflated.

I suspect when you get a leak the compressor starts working overtime eventually overheating and stop due to thermal protection switch. Fix the leak soon enough a maybe save the compressor.

I was driving down the highway when my GLS suddenly began bouncing and the Air Suspension Malfunction indication came up. I pulled over and rear side of car was lowered. Any ideas on what it could be? I will troubleshoot the issue in the morning but wanted to get some ideas to know where to begin. Thank you.

Failed air spring ("air bag"), air line, compressor or level sensor. Read OBD codes and crawl under the vehicle for a good inspection. See if the car maintains level overnight.
