There is little to no chance that it's
bad again. I've talked to suppliers and
although they take returns most tests
show the temp is not to blame.

Why is the fan not running?

I went through this with a gauge that
was too high but replaced the radiator,
temp sender, wiring, new grounds ect.
And still the gauge was high.

You can take ohm readings to test the
sender and I built a resistance box to
test the gauge. Found out my gauge was
just to sensitive in its old age.

You need to check grounds from the gauge
(brown) to the body as that ground
cluster behind the dash on the drivers
side can cause issues. If I recall high
resistance means lower temps. Therefore
a connected by bad ground could be at
work. I also ran new wires from the temp
sensor to the gauge.

If you need specifics I have lists I've
made of resistance at given water temps
to help trouble shoot my issue. Did lots
of work because specific values are hard
to obtain from vw, EDO and Bentley.
