w140 hydraulic pressure to rear self leveling suspension
on the V12 uber alles site talking about the real self leveling suspension it references the pressure in the system. My 98 s500 system has always not absorbed the road bumps very well and it seems the system is harsh in the rear. I replaced the rear accumultors but the ride did not improve much. In the DIY article it says the fluid is under a lot of pressure, but when I disconnected the lines between the strut and the accumulator, the fluid did not seem under any pressure. When I started the car to drain the system, It did flow out but not under much pressure. Just came out slowly. When I open the resevoir it is pumping back into the system but the flow is not at very high pressure. Just kind of pouring back into the resivoir. What pressure should this system be under when the car is running? Do I need to replace the tandem pump to improve the ride?

You may very well have issues, but, keep in mind that in general terms flow volume does not have to be high for pressure to be high. In other words, the pump may be pushing the fluid slowly, but it may very well be pushing it with plenty of force. Your brake system is a perfect example of how very little fluid flow can generate tons of force.

there is only about 1/2 inch clearance between the right rear tire and the wheelwell where there is about 2 inches on the left rear. Seems to indicate the right strut/accumulator/spring? is different than the left. Does that ring any bells with anyone?
