EGR valve sensor

[Delpel1]

Now then folks, I've just had my EGR valve changed and a minor service on my T6 T32 150 DSG. Drove it back from garage and all was good. Took it out today and I was getting a whistling sound when I accelerated. Got home and had a looks ie. Found a sensor completely dislodged in front of the corrugated pipe on said EGR valve as per pictures.
What is the sensor for and could it have caused any damage by being dislodged like that.
Needless to say I am going to be having a conversation with the garage.

Pressure sensor i believe?

Reserved.... EGR, EGR cooling, EGR bypass...

❆❆ EGR normal cooling and EGR cooler bypassed​

From 0 to 200 seconds reported EGR position > 0% thus EGR cooler bypassed. This cooler bypass happens always after engine start, even in summer conditions. [EDIT: 20.4.2024]

From 200 to 1100 seconds reported EGR position < 0% thus exhaust recirculation through EGR cooler.

From 1100 to 1800 seconds reported EGR position > 0% thus EGR cooler bypassed (also seen from 0 to 200 seconds).

The transition seems to take place somewhere at 0....+5 °C.
