Wires or ecu connection if you said the sensor was tested
you didnt understand what has been written before
the sensor in the car does work. its a shared sensor where 2 wires go into the ecu and two wires go to the cluster.
the ecu shows temperature and the cluster shows temperature. the wiring and the sensor is okay.
i modified TMELIPU1 to all 90s and the result with a new sensor located loosely in the engine bay is that the cluster and measurement block shows 90 on ignition on.
when you drive the car the cluster will switch to 60 (lowest possible value on the left).
I chose TMELIPU1 because there was -40 as a max value.
So it looks like the cluster is feed from the ecu in some conditions. I thought the cluster is always feed from the sensor itself like it is on 1.8t cars.
