To get my speedometer out this is what I did: I removed the kick panel which is about 3 or 4 screws at across the bottom of the dash about even with the steering column. You probably also have a plastic retainer (gray plastic) with a phillips head that you twist once to either left or right and it slides out. The kick panel is a little difficult to get out without alot of twisting and pulling but it comes out. Once out, you reach up through the space behind the instrument cluster and push it from behind and believe it or not, the whole instrument cluster pops out with very little pressure (the rubber gasket that slides around the instrument housing provides a "pressure fitting" of sorts to hold it in. Then you can pull it out just enough to unplug the wires to the warning lights, the fuel/temp harness plug and the wires plugging into the back of the speedometer (cruise control?). I think there might be one more wire connection on the right which is the clock. Then all you have to do is take a 10mm(could be 11mm?) wrench and unscrew the brass oil pressure guage line. Next you undo the speedometer cable with channel locks or something else that has somewhat long handles... being careful not to bugger it up too bad! Once that is all undone, the whole cluster will come right out. Looking at the back of the cluster from above, you will notice that there are three different panels that house the fuel/temp/oil press. guages on the right, the speedomter/odometer in the middle and the tach/clock on the left. I believe I am correct stating that you take out the left side first (4 screws) and then remove the tach/clock panel. Then undo two screws that still hold in the speedo on the right and the speedo should come out fairly easy but be careful, you don't want to fold/spindle or tear the speedometer needle, etc. Once you have that jewel in your hands, you remove the cruise control fitting whereupon you can remove the two brass flathead screws that hold on the speedo protective housing. Once that is off, you are ready to do your business with the repair like what I referenced in the earlier post. I have a friend with a beautiful 240D that is stuck on the .9 and I cannot wait to get my hands on her to fix his too.... it's not that hard as I am surely no Mercedes scientist but I am not afraid to attempt things so I can learn! It is truly therapy for me. Hope this helps.
