Hi,
I have a constant 220 degrees C and O Volts signal on Exhaust Temperature Sensor 2
Can anyone help me here, where is the sensor, is it most likely an open circuit or do these often break?

Can anyone help me here, where is the sensor, is it most likely an open circuit or do these often break?

The fact that there is no DTC for that sensor (with those implausible values) possibly indicates that it is not fitted to your engine and you are looking at substituted values !

No that makes sense, as its not throwing any codes related to the EGR or Particle filter.

Thanks

Unlikely an EGT would, in the first instance, throw an EGR or DPF DTC. These cars are very good at looking at the EGT's and throwing accurate DTC's


Looking at the data from your car:
IDE03270 Exh.gas temp.sen 1: unconditioned voltage 1114.6 mV
IDE03271 Exh.gas temp.sen 2: unconditioned voltage 0.0 mV - This would be flagged up !!
IDE03273 Exh.gas temp.sen 3: unconditioned voltage 1004.6 mV

IDE05387 Exhaust gas model temperature 1 86.6 °C
IDE05388 Exhaust gas model temperature 2 93.3 °C
IDE05389 Exhaust gas model temperature 3 -20.0 °C - This looks wrong ? !! However No DTC so take it as a red herring for now.

its common that a VW/Audi had EGT-sensor mentioned number 4, but only 3 times fitted in the car, then for example, only 1,3 and 4 are fitted, sometimes reading -40deg for (missing)sensor 2

You car has 3 according to Partslink,
1 in the turbocharger
1 before DPF (brown connector)
1 after DPF (black connector)

For a month or 2 ago i had an SQ5 in, there was the last EGT sensor after DPF broken, probably something underneath the car hitted the end of the sensor/begin cable

Yep !! We have been there many times.


Happy to help !
