Rain/light solar sensor: Notes
WARNING: This page is about a different car, the 2013 BMW X5, 2012 BMW X5, and 2011 BMW X5. However, it is still accessible from the selected car via links, so may be relevant.
The rain/light solar sensor groups the following sensors and components into one control unit:
- Rain sensor: consisting of 3 individual sensors arranged in a semicircle around the driving light sensor, picking up the precipitation quantity on the windscreen.
- Driving light sensor: consisting of 2 photosensors that pick up the brightness of the ambient light and of the frontal light. On the E70, the front light sensor regulates the brightness of the Head-Up Display.
- Solar sensor: It consists of 2 photosensors that measure the intensity of the sunlight for the driver's and front passenger sides.
- Electronic component: It evaluates the sensor signals.
Requirements for trouble-free operation of the rain sensor are:
- Wiper blades OK
- No streaking on the windscreen
- Sensor area free of dirt contamination (road salt, insects)
- Windscreen in the area of the rain sensor without faults (stone chipping)
- Optical element bonded free of bubbles with the windscreen glass
