Hi Art, your site has been my bible for years!!! And here is the right occasion to thank you for your great work!!!
I totally ignored EU 240 don't sport a compensation board.. but I suspect that >92 cars sold in Italy with the name Polar and PolarSuper have a lot in common with USA Limited Edition, so maybe ODO and Tach box (in KM of course). My mechanic who was the head of maintenance in an old Volvo dealer, suggested some failure in the compensation board, and I am sure he never have seen an American one! :-)))
But let's assume you are right (and I think you are...) the only check I can do to solve this misalignment between what the hand says and the measured temperature is the sensor and its wiring. Am I right?
