Mercedes-Benz A-Class W176 Rain Sensor

The rain sensor in my car is not activated.
Do you know how to activate it with Xentry? Or is there a guide?
I don't know if this part is correct.

Activate code 345 in N73 (EZS).
If the rain sensor itself is present, it will work. It may just be a light sensor.
