    bad gauge motor. really all this gauges are digital. Sometimes motors fail with dust and the only way - use donor motor.

    Before I change sending unit I use service link software to see acyual values. You understand. Well, bad motor is volvo issie usually. Ok. look for bas dashboard on JY and change the stepper motor. If not - may be you got driver chip bad. It must be resoldered with hot air. it is for electronic technician deal

    It is not so easy. Motor is soldered in board. It is 4 pin plastic motor with 0.4 mm axe, to disassemble panel is not easy, you can damage other motors removing gauge niddles. Look for someone who fix dashboards pf trucks and cars
