The car is X-Type 2.0 Diesel. In the manuals a minimum voltage is shown on the 12 Volts injectors but it is possible that it refers to the other X Type models and not to the diesel one. With the key off there is a constant voltage of 0.65 volts, with the key in position II (ON) 5.4 volts, with the engine on, always 5.4 volts. I would like to know what tension to work these injectors.
