Component Identification:

Location
The dual sun sensor is located on the dashboard behind the center nozzles.

Task
The dual sun sensor is only processed by the comfort AAC [KLA] control and operating unit (N22/7). The dual sun sensor is capable of measuring the intensity of the radiation (brightness) of the solar radiation with the aid of a photodiode.

The dual sun sensor differentiates between left and right solar incidence, in other words it has two photodiodes. The interior temperature and the blower stage are adjusted based on the intensity of the light.
Among other items, evaluation of the sun sensor depends on whether an infrared insulating windshield is installed.In this case, the values read in are evaluated at a rate of only 66 % for control.
