Ineffective blind spot system.
Gents.

I have a problem with my "blind spot function" The system reports "system inactive" and the triangle in the mirrors lights up constantly yellow.

How do I find out which one of the 4 sensors is defective?

And what is the recommendation regarding the replacement?

Good weekend.
