Is your car equipped...
with the digital climate control, or the European set-up with the rotary temp dials for each side?
If you have climate control, there are a number of posts on trouble shooting the A/C system in the W210 forum.
If you don't have the climate control system, a tech can tell quite a bit from attaching a set of manifold gauges to the system during a re-fill.
