GL 320 Air suspension
2008 gl 320.
front air struts replaced a year ago. Air compressor replaced 6 months ago. Noticed this morning that the front end both sides was setting very low. Just a few inches above the tire. Drove it around with no malfunction message but it never rose to the right height. When I parked it I tried to raise it with the ride height button and got the message that compressor was cooling down.
I can hear the compressor come on. And I am not hearing any air leaking like I did before replacing struts a year ago.
im think maybe air compressor filter or air compressor valve block?
Thoughts?

Either compressor saying bye bye, or there is a leak in the system. Had same issue yesterday. Rear left bag been sagging. Will replace it tomorrow. If things won't improve will replace compressor on wednesday. Will let you know

I just have a hard time thinking it’s the compressor since it was replaced in March and I can hear it coming on. Could there be a issue or leak in the hoses or valve black coming to and from the compressor casing this? Also does anyone know if my rear end has air struts on this model? Seems like if it did and the compressor was going out it would affect the back end too and it’s not. It’s only front

You have a X164 GL. This is the correct forum. https://mbworld.org/forums/gl-class-x164-77/

So far in my case turned out to be busted front air strut. Compressor pumps and shuts down due to overheat and i can hear leaking air from front strut
