Just stumbled across your post. I can say that on my 80 300SD, I had to replace Both the tach amp and the sending unit. If these don't fix it, then you could have bigger issues.

Use the old 2 cent fix. Pull the tacometer off in the engine bay, separate the pin connector from the casing it will pop off with some force, then add 2 or 3 pennys into the cap and reassemble. Cheapest Mercedes fix you will ever encounter.
