As for the fluid leaking out of your shock, you would be able to see it. It wouldn't be a steady stream or anything like that. Just fresh fluid on the outside of the shock housing. Typically coming from the seal where the two parts of the cylinder meet. (in the middle).
I have a '85 500SEL Euro and have the hydropneumatic suspension on all four corners. I noticed that I have a hydrostrut on the front that has a small leak in it. I'm going to have to replace it.
84 500SEL EURO 87K
85 300D 267K (and still goin' strong)
