Location of the IAT (G42) and Boost Sensor (G31) Sensor

Hi,

On my 2.0TDI (PD140 BLB) Engine,

Where can I find the Intake Air Temperature Sensor (or is it just another name for the MAF/MAS by airbox)

and the Boost Sensor (or is it another name for the MAP/Thrust Sensor by intercooler)

18000/P1592/005522 - Altitude Sensor / Boost Pressure Sensor: Implausible Correlation
16497/P0113 - Intake Air Temperature (IAT) Sensor 1 Circuit (G42): High Input

Thank you

Air intake sensor is part of the airflow meter
Boost sensor is normally in an intercooler pipe on the high pressure side of the turbo

To be honest if you change the air flow meter you will prob find the boost sensor fault will go as the air flow will affect the boost

Thanks,

A mate just showed me on Elsawin that the g31 and g42 is the same sensor on the 2.0TDI BLB engine, which is the MAP/Thrust Sensor at the intercooler.

The thrust sensor (combined MAP/IAT) is on the intercooler under the left headlight, part number 038 906 051 C, Bosch 0 281 002 401
