Speaking of which....

A while back I suspected that my temp sensor was going haywire. (the
half that connects to the ECU) I tested the resistance every 10
degrees (pic of fetid test method  http://tinyurl.com/299hpdh  ),
while heating up each in a pot of water. I did this with 3 different
sensors; the "Luxembourg" (OEM?) used sensor, the newer suspect one,
and a new FLAPS brand sensor. They all gave slightly different
readings at various temps. The Luxembourg being closest to the graph
in the A3 Bentley This is for my Jetta swap, but IIRC, graph is the
same for the WBX.

I suspect that a WBX OEM temp sensor, and a FLAPS obtained sensor, may
suffer similar differences.
