Hi I looked but did not find... Is there a write-up on how to replace the tempature gauge on the car? I have a 98 1.8T, it works, I just don't belive the gauge is true to the tempature! How much do they run?
TIA

I don't know where the write up is, but I do know the guage is on a bracket near the lower middle front of the radiator. Mine was reading really high on hot sunny days. I found out that the bracket that the held the gauge was broken and the gauge was hanging in front of the bumper and therefore not getting much air flow. I ordered a new bracket, but haven't received it yet. Check to see if your bracket is broken. Part number is 8D0820536C.

Did you have to take off the bumper to access it? Or are you able to get to it easilly?

i dont think mine is working right either, it said it was 112 outside today, but it was only 90.

... but it was only 90.

Only?!?

The temp gage is located in front of the lower end of the radiator. On my B5.5 1.8T I can access it by just pulling out the middle third of the lower grill. There are two parts: (1) a "harness" that terminates the wires and allows the sensor to plug in, and (2) the sensor itself. The sensor is a thermistor (a resistor that changes resistance based on temperature). I don't have the p/n's handy, but let me know if you need them and I'll check again. (Your p/n's may be different from mine if you don't have a 2001.5 B5.5 1.8T wagon).

I have been tinkering with an intake temp gage wired in parallel with the ambient temp gage - I ended up going with a non-vw thermistor ($2) instead of the OEM VW part for approx $80. :shock:

I have a 98 1.8T, auto... is there a write up/pics or nything?
Thanks pete

No write up... it's just plug-and-play with the sensor: pull the old one out of the harness and put the new one in. I'll take a pic tonight and post it.

Do you have an ohmmeter or multimeter? We can check the sensor's resistance/temperature curve to see if it's still working correctly (indicating a wiring problem somewhere else in the system).

Also depends on what you are driving on. Sitting in stopped Atlanta traffic I saw the guage hit 103 and on black asphalt it ws probably true. Temp according to am radio was 92. If you were on grass it wouldn;t be so bad.
