Hello,
For 4-cylinder engines that are not PD TDI, the charge air temperature is located in measurement block 7 of the engine control unit.
1. Fuel temperature sensor in the fuel injection pump.
2. Value: N/A
3. Value: Intake air temperature / Charge air temperature.
4. Cooling water temperature value.
You should have been able to figure out that the diagnostic tool cannot measure Nm at the wheel, because there is no corresponding measuring device present

.
If something like that is displayed, it's a value stored in the engine control unit that has nothing to do with reality.
Best regards, Rainer.
