Has anyone replaced their own rain sensor?

Mine stopped working, ive done my search some say i can reset it using NCS-expert but which module is the faulty code stored in?

My car is a 2006 525i with N52 engine pre-LCI

 

Update I fixed mine turns out the sensor was never broken it just needs a re-initialisation.

I don't know why but here is how to do it using INPA.
