Question Problem 2007 SL550 suspension noise

a few months ago I had a leak in a suspension hydraulic line and my mechanic replaced the line and recharged/filled the system. A few day ago, I heard a sound under the hood like a pump not having fluid. Also, when I start the engine and the car raises up as the shocks are being charged, I hear and feel a clunk at either the right front of left rear of the car.
Could it be the suspension hydraulic pump dying? Why the clunking sound and shake?

Thanks,
Brian A.

Could be front valve block needs a rebuild. Sounds like the pressure is not holding. Of course, a diagnostics reading would help.
