[W126 Coupe] Help me narrow down self leveling problem

[Matt Jurcich]

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
