It can be a general offset like Roland mentions it but I believe in missing power to "pull the needle up". Get the cable connectors down from the impulse transmitter at the ZF gearbox, clean/scrape everything very seriously incldg. the covering "rubber condome", look that the cable plugs are strong in place and not bridging by contamination at both sides, that should be it for most cases.
If not you have either electrical restrictions inside the dash unit plugs, bus foil or pin connectors into the speedo unit at the dash. Last not least there is an adjustment poti at the speedo unit itself, but like I mentioned above, the cleaning at the ZF gearbox switch only solves it.
