Our friend at the source of mercedes did a PDF on this, I read it.not long ago. I would suggest reading it, he goes into the reasons why one should.not adjust the valve to chang3.vehicle.height. longstoryshort, your problem is mechanical in nature, not hydraulic. The springs, differential mount, and or subframe.mounts are worn, none of which has anything to do with the hydraulics. The hydraulics are.for dampening, and adjusting the height if you have a Load. If your car is not loaded, then you have other problems.
