Today something from the front bumper passenger side started making very loud noise, and especcially when my car is raising, could it be suspension compressor? If yes should i get another one or it could be repaired? And how much it would cost for me?

I'm pretty sure it's the airmatic pump pressurizing the system. It shouldn't be loud all the time it happens in my car too.

Probably around $900 to have your dealer replace the pump.

from what I know, the pump is attached to the car on some sort of rubber bushings. I heard my friends S class, with the rubber piece missing...boy it rattled inside the car everytime the pump turned on...a worn rubber bushing might give off the same sound....better investigate ...$112 part

If it's cold out that would do it. Mine did it the past to days its been 40 out in Florida. I know I sound like a wuss but thats cold to us. Its just the pump it'll go away...or will it.

112$ for which part? Compressor?? Cause the guy at car shop told me that it has to be replacable 340$ Suspension compressor and 130$ labor

Old pump. If it bothers you, replace it.

I have the same issue, and I'm just gonna use it until it busts before replacing.
