[W126 Coupe] Help me narrow down self leveling problem

Matt,

Check your Accumulator's, if they are leaking then that is your problem. They are located under the rear of the car and are oblong and black in color. One on each side.  If one is leaking you need to replace both of them.   It should be a firm but yet not to soft of a ride if that makes sense. If the back end is bobbing a lot then most likely the accumulators are bad.  Typically they leak when they are bad indicating that they need to be replaced.

  Hi all,

  I've been reading many many threads on the rear self leveling suspension.  Lots of great info out there.  My car, however, doesn't seem to fit the typical symptoms.

  Car is level and the ride is too soft.  I have fluid in the resivoir.  If I load up the trunk with the car on, rear does not react at all.  I got under the rear end, found the valve and with a wrench moved the level up and down and didn't get any reaction either.  

  How long does one need to hold the valve lever in the up or down position to expect movement to start?  I only held it there for a few seconds.

  I don't want to just start throwing parts at it--way too expensive for that!  I will check the filter in the resivoir tonight.  The leveling has not worked since I purchased the car a couple of months ago.  The rest of the car is in great shape, everything works on it (Even cruise control!)

  Thanks for any suggestions on what to look at next.  89 560 SEC
