Windscreen Rain (and Light) Sensors: Audi



This is how a properly installed rain sensor should look:

Correctly fitted


If the sensor gel pad is missing, it will affect the sensitivity – or functioning – of the sensor. Many windscreens are being replaced, and the sensor pad is not renewed. The auto wiper function may still work, but it will not be as responsive, and sharp, as a sensor fitted with a gel pad.


Without Gel Pad

Incorrectly fitted

Active Lane Assist, or Lane Departure Warning cameras are fitted differently and will not require a gel pad.

  3. Hi,

    Any good guides to change the Silicone Pad on my Audi A4 B8?

    As in how do it remove the sensor to get to the pad; Is the pad adhesive stuck to the sensor or onto the screen?

    I think my pad has broken down or is missing
