And if you know how that plastic cover over the temp sensor works, feel free to put in a tip about it.......remove it without breaking it...
Ping the two metal wire clips on each side of the connector and pull. It will come right off the sensor.
The temp and fuel gauges senders will have waaay different resistances. The Fuel gauge resistance from the sender should be between 50 and 350ohms iirc. You can try grounding out the fuel sender to see if the gauge goes up to full, but it requires:
- lifting the trunk carpet
- removing the three sheet metal screws over the round fuel pump access panel
- unplug the connector on the fuel pump
- connect the fuel gauge sender wire to ground and the fuel gauge should peg fuel with the key on
The key has to be on and make sure you don;t ground out the +12v fuel pump lead.
If the gauge didn't work in the passat though, I would presume there is something screwed with the gauge itself. I have experienced, unpluging and re-plugging in the gauges to help issues on occasion.
