Rain and light sensor: common housing with different functions

Useful to know

HELLA describes a combined rain, light and climate data module that can include solar load, humidity and other functions. They are combined according to vehicle requirements. [1]

Therefore, a similar housing in glass does not prove uniform equipment in all versions. Automatic wipers and automatic lights are separate reactions. If one works, it is not a complete test of all other functions. In description, indicate exactly which automatic operation behaves unexpectedly and under what conditions.
