Unfortunately on the W124, replacement of the center vent vacuum diaphragm requires removal of the dashboard. What you can do to test it, is pull the glovebox liner and look at the manifold which has a bunch of lines coming off it - hook a MityVac up to the one that controls the center vents (I forgot which one) and see if it holds vacuum. Actually, check to see if they ALL hold vacuum - which they should.

If you're pulling the dashboard, you might as well replace all the vacuum pods...
