560SEL Self Leveling Suspension

I have over the last few months been replacing components on the rear suspension, I just replaced the Self-Leveling Pump (new FEBI Bilstien OEM) mounted to the engine, but the rear is still not working. So far I replaced both rear nitrogen chambers (Lemforder OEM), rear valve (new MB OE), sway bar links, both rear accuators/shocks (Sachs OEM), filter/fluid. the rear is still not working. When I open the fluid chamber I can see a stream of fluid coming into it (I also saw that with the old pump installed) so I assume there are no clogged lines. When I open the bleed valve on the rear level valve a good stream of fluid comes out and it is not "foamy". I dont think I have anymore components left to replace, except the rear springs and the fluid lines. There are no fluid leaks and the res. level does not go down. After I replaced the pump yesterday I went to the rear Level Valve Disconected it from the sway bar and moved the lever up and down with no effect of the rear height.

What is left to fix.

Chris

You have to reset the system. PUt a couple of guys in the trunk, total 250 lb`s. Start the car and run at 1500 rpm`s. the guys in the trunk will feel it rise. Then your all set.

Hoopster,
How did it work ? What really happens is that your moving the arm on the valve at the rear. This lets fluid flow to the accumilators and shocks. It`s the same as if you loaded the trunk with luggage.

No luck with the fat guys in the trunk. Still sitting low. Could it be that the rear springs have collapsed? Could the sub-frame mounts be collapsed, if so would this make it sit low? I dont mind replacing the parts, just getting a little tired of the expensive ones (however I think I have covered all those).

If there are no leaks, it`s probably the shocks. They are exspensive.

Did you put the guys in the trunk and then start the car and hold it at 1500 rpm`s or more? It has to be done that way.

I would take it to an MB tech to at least diagnose the problem. Then you can decide if you want to fix it yourself or let him. At least you`ll know what the problem is and save some $ instead of throwing parts at it.

Guys in trunk first ran at 1500 10+ minutes. Rear shocks new OEM Sachs, I replaced less than thousand miles ago, and yes they were expensive. Next step is to the professionals...

Thanks for all the help
