OK now I'm really lost. I have an '83 500 SEL Euro with the pneumatic suspension. cable seems to be a little stretched but with the lever pulled all the way out, the suspension goes all the way up and rides like a buck board,i.e.(hitting my head off of the headliner while going over bumps) my wife thinks it's comical when she is following me down the highway . When I push the lever all the way in, she drops to about 3" from the road. Sorry,can't run down the road with the cat. dragging . Is thier anykind of adjustment or am I screwed unless I spent the $$$ to switch over?? This vehicle will be for $ale as soon as the new rubber is installed and the inspection is complete,which should be in about a week. I would prefer to have this fixed before I put her up for sale. Can anyone help????
