Not correct. Some exhaust temperature sensors have had their lower limit +75 C.
Obviously the sensor is somehow faulty - having a significant offset? Surely worth to replace (as triggers a fault).
Difficult to estimate correctness as exhaust gases right off the engine are fairly hot anyways, especially if the engine was still starting a DPF regen. Also the log is too short to catch possible glitches (between 0 and 300 seconds).
Have you synchronised van's clock and VCDS PC clocks as recorded fault time in the log is 17:01:04 and VCDS log at 300 s is 18:02:06 (obviously van is still in standard time).
It seems that indeed the fault freeze frame data was captured at 300 seconds but quite possibly actually missed the triggering "implausible signal" - possibly sometime well before 300 seconds.
Makes me think that you shutting engine off before 300 seconds inhibits the fault suggests the glitch happens only quite early
Would be interesting to capture actual sensor voltages by recording the following + a selection of yours
IDE07712 Turbocharger 1 turbine input: temp. sensor 1: B1: raw value
IDE07713 Turbocharger 1 turbine input: temp. sensor 1: B1: raw voltage
IDE07714 Turbocharger 1 turbine output: temp. sensor 1: B1: raw value
IDE07715 Turbocharger 1 turbine output: temp. sensor 1: B1: raw voltage
IDE07716 Particulate filter input: temp. sensor 1: bank 1: raw value
IDE07717 Particulate filter input: temp. sensor 1: B1: raw voltage
IDE07718 Particulate filter output: temp. sensor 1: bank 1: raw value
IDE07719 Particulate filter output: temp. sensor 1: bank 1: raw voltage
Just noticed something very strange in the blockmap (engine OFF) voltages (voltage to temperature conversion)
IDE07712 Turbocharger 1 turbine input: temp. sensor 1: B1: raw value 191.7 °C
IDE07713 Turbocharger 1 turbine input: temp. sensor 1: B1: raw voltage 4.857 V
IDE07714 Turbocharger 1 turbine output: temp. sensor 1: B1: raw value 7 °C
IDE07715 Turbocharger 1 turbine output: temp. sensor 1: B1: raw voltage 4.858 V
