Hi, I noticed that my car (A4 B8 2.0 TDI 143hp 2011 NFL) has a humidity sensor and I would have some questions about it and the light and rain sensor.
1) What does that humidity sensor do and how would it affect it if I disconnected it and left it like that.
2) I bought the light and rain sensor together with the light block and I would like to know if the sensor works when I disconnect the plug from the humidity sensor and put it in place of the rain and light sensor (with the corresponding coding). adaptations, other wiring in place? If it went on the same wiring as the humidity wiring, I would be willing to give up that sensor and I would like to know, as I said in the first question, if it affects anything. Thanks!

EDIT: I can show some pictures in case the situation is not understood.

This are the photos with the connectors, the blue one is from humidity sensor and the black from the light/rain sensor.
I trim the little edge from the blue connector to fit in the light/rain sensor connector but i forgot my VCDS back home and i cant make the code today.
