Hello guys,

I own a 2003 S500 4matic with Airmatic and the last two days I´m getting this sound noise like
when the Airmatic system gets rid of the excess of pressure. The only thing is that it happens
all the time. Whenever I take a fast turn or I drive over some pothole (not big) I hear this air hiss
like air is released from the system. I have also noticed that the right front wheel doesn´t go up
all the way as the left front wheel when I press the "rise button" in the dashboard.

Also I hear the Airmatic compressor working much more frequently than before.

Valve block? Any hints are welcome.

The Air Bags work by rolling over themselves when they get lower, thus they can seal themselves, then as it tries to raise it exposes the leak that is why this happens as you are saying .
