Right....this has got me confused as hell!! Been having issues with my gauge and random misfires....so replacing both the sensors seemed a logical start.
However....I thought there were 2 separate sensors for the coolant.
1-Coolant Sensor - Sends a signal to the ECU (has 4 wires)
2-Coolant Sender - Sends a signal to the dash gauge (has 2 wires)
Well not according to Audi there isn't. Apparently there is just one located in thermostat housing that covers both?!?!
Can anyone clarify this? And post a link of which one I need please
