    Thread: Fuel gauge and temp gauge not working. 92 vw cabriolet

    1. 02-28-2012 12:11 PM #1
      I love my 92 VW Cabriolet, but my fuel gauge is stuck on E and refuses to move. I have been using the odometer to keep track of my fuel, but it is getting annoying ! Also, the temperature gauge doesn't move at all. Can anyone help me solve these problems? Thanks!

      It could be that your fuel level indicator on your instrument cluster could be bad.

      Temperature gauge, do you mean the Oil temperature level, where it says Celcious?

      Yes, I meant the oil temperature gauge where it says celcious.

      check the fuel sender in the pump assembly, its under the rear seat, on the right side.

      change the coolant temp sensor, its on the coolant flange in the head, its the black one.

      I've read a bad 10v transformer on the back of the cluster..can cause this, leaving the cluster parts not working.

      Correction..if just the fuel gauge on the cluster isn't working, then i'd suspect the sending unit in the tank.

      If the oil temp gauge isn't working, I'd suspect its not plugged in to the sensor correctly or the gauge has died.

      Could be a bad gauge, or a sensor in the car. I bet its a bad sensor.

      DING DING DING... we got a winner here folks.

      There are 3 threads that deal with this issue that I wrote,

      How to test your Gauge with out having to remove crap from your car.
      Take the connection off the black sender in the water outlet flange, and use a 9V battery
      Jumper the wires fro the battery to the sender. The gauge will deflect 3/4 to full (key is not in the ignition.

      Your 10V voltage stabilizer is probably bad, or not getting the voltage off of pin 12 (black) on the back of the cluster.
