Brief component description: Notes

The rain/light solar sensor is inserted from the inside of the windscreen in the wiper range of the windscreen wiper. The rain/light solar sensor is fixed in the bracket by a steel-plate spring. The bracket is firmly bonded to the windscreen. There is a gel pad between the rain/light solar sensor and the windscreen. The gel pad is fitted on the optical element (new part). The silicone gel provides the optical connection to the windscreen and prevents dirt from entering. Important: After installation of a new rain/light solar sensor, the gel pad can no longer be removed without damage, rather the gel is destroyed.

This installation location ensures that the windscreen surface in the area of the sensor remains free of dirt and ice. To prevent the sensor surface from fogging over, the sensor is heated.

The rain/light solar sensor is supplied with voltage from the roof function center. The signals of the rain/light solar sensor are transferred through the data buses.
