Removing and Installing Rain Sensor

Removing And Installing Rain Sensor







Removing Rain Sensor







Limited functionality of the rain sensor when the following information points are not observed:

NOTE:
- An adhesive pad must be used when reinstalling the rain sensor.
- When assemblying the adhesive pad, air should not be trapped between the windscreen and the adhesive pad or between the adhesive pad and the rain sensor.
- When installing the adhesive pad, a temperature of approx 20 degree C for the windscreen, the rain sensor and the adhesive pad must be ensured. Carefully heat the windscreen with a hot-air gun for example.
- The sensor on the sticking surface must not be touched by fingers.
- If the sensor is new, remove the protection cap before the sensor is stuck onto the windscreen.
- When sticking a new sensor, make sure that no air pockets are caught between the gel and the windscreen. Air pockets could impair the function of the sensor.
- Sensor, orientation lights, wires and wiring ducts are spare parts.

If the old rain sensor is installed: begin with the instructions.













Installing rain sensor







NOTE:
- Observe notes.
- If the removed rain sensor is reinstalled, the surfaces must be free of adhesive residues. Do not use harsh cleaning agents. Stick the adhesive pad onto the rain sensor at a temperature of approx. 20 degree C.













Open circuit in the rain sensor connection (emergency interval operation)

NOTE: The rain sensor control module independently detects a faulty rain sensor. Fixed intervals are allocated to six sensitivity stages (wiping interval stages) as a remedial measure.

1. Ignition on and activate rain sensor.
2. If the windscreen wiper switches on intermittently, the rain sensor or the wiring must be checked and replaced if necessary.
