[W126 Coupe] Help me narrow down self leveling problem

[Matt Jurcich]

Should I be seeing any movement when working the valve lever if the
accumulators are shot?  I have located them and visually seemed fine,
although I understand the leak for these is between the two interior
sections of the unit.

Some have recommended removing the oil line from it, and sticking a
screwdriver in and seeing if it only goes a couple inches in to feel for the
membrane.  Is that reliable or should I just change them?

Thanks!!
