Gas gauge and Temp Gauge


Recommended Posts

Hello Guys,

I wonder if this ever happened to anyone or if such thing is a common issue in these babies.

My gas level shows empty at all times even tho the tank is full - and the E light flashes

and my temp gauge shows below 100 at all times

note that the speed gauge works fine as well as the RPM gauge

the digital showing of the speed is working well yet the temp is always at -----f

I wonder what it has to do with, either the cluster or possibly some other issue i cant think of and what would be the solution to such issue?

Thank you.

If you had a 2002 I would have a good guess on the fuel gauge. There is a fuel level sensor/float in the gas tank. The float gets hung up on a hose in the tank and you see a false low level on the gauge. To fix it the hose is tied out of the way so the float does not get hung up. Porsche issued a TSB for this very problem.

But your profile says you have a 2000.

A mechanic told me how he figures out the problem. If your car is hooked up to a PST2/PIWIS tester you can make the fuel gauge needle swing smoothly back and forth, from full to empty and from empty to full. If it does not then the gauge is faulty. You can also test the low fuel level warning light.

If the fuel gauge functions properly with the tester then you remove the sender from the gas tank. You then operate the sender manually and check to see that the gauge needle moves smoothly from full to empty, and from empty to full. If it does not, then the sender is faulty.

With the PST2/PIWIS you can also test the coolant temp gauge.

You should also state the history of the problems in case someone has a better clue.

I just bought this vehicle so i have no previous history on it.

The carfax report came clean with no known major work done on it.

I assumed right away that the instrument cluster is faulty due to the fact the both gauges that are located in the same cluster area are not working.

Its just a scary thought to take this car on the road with out an engine temp indicator.
