Removing rain sensor

Information 

• An adhesive pad must be used when reinstalling the rain sensor. 
• When fitting the adhesive pad, make sure there is no air trapped between the windscreen and the adhesive pad or between the adhesive pad and the rain sensor. 
• When installing the adhesive pad, the temperature of the windscreen, rain sensor and adhesive pad must be approx 20 °C. Carefully heat the windscreen with a hot-air gun for example. 
• Do not touch the adhesive surface of the sensor with your fingers. 
• If the sensor is new, remove the protection cap before sticking the sensor on to the windscreen. 
• When sticking on 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.
