Where is the coolant sensor located on the 3.2 A6 I think there might be 2 of these sensors one that sends signal to ECU and one that sends it to the gauge. I need help locating these . . .

 

Nobody knows??

 

The ECT (G62) is in the plastic coolant crossover tube on the front of the engine, towards the right (pass) side of the car. Going off the top of my head here, I believe the same sensor is used for the gauge indirectly from the ECM through the gateway module and then to the instrument cluster module.
