I was thinking a short in the wire from the sender, but that wouldn't make sense, since vdo uses a higher-pressure = higher-impedance sender. Maybe a bad ground?
Do you have a multi-meter? First, I would unplug the wire from the sender, and test the impedance of the sender, to see if it was at the correct level for zero pressure. If that's all fine, I would plug it back in, and go pull the gauge, disconnect the ground and sender wires from the gauge, and test impedance across them. If the first measurement is ok, and the second isn't, you have wiring issues, either on the wire from the gauge or ground.
