If your car was origianly distributored then you will have to screw around a bit to get your dash tacho to work. They work on the voltage spike from your coil. AFAIK, the microtech will be outputting a 5V square wave for the tacho.
So plugging your microtech tacho output into your stock sprinter tach wont work. I tried this and had my tacho going with my indicators.
There is a reasonably simple fix, so if this sounds like your situation then let me know and I'll send you a circuit diagram.
