Removing and installing rain and light sensor -G397-
The rain and light sensor has been designed so that it can be used again. The prerequisite for the re-use is that the coupling pad is not damaged (check!).
  Caution
On removal, store the rain and light sensor -G397- in a dust-free location until reinstallation and ensure the silicone contact pad is not soiled.
  Note
t  If a rain sensor is renewed and has to be replaced by a rain sensor with another part number, the rain sensor must be coded → Chapter.
t  The rain sensors cannot be installed optionally. Determine the right sensor according to ETKA (Electronic parts catalogue).
Removing:
–  Switch off ignition and all electrical consumers and remove ignition key.
–  Remove interior mirror → General body repairs, interior; Rep. gr.68.
   
–  Disconnect connector -A- from rain and light sensor -G397--1-.

–  Using a suitable plain slot screwdriver, lever rain and light sensor -G397--1- on recess -3- out of retaining plate -2-.
  Note
On removal, take care to lever out the entire rain and light sensor -G397- and not just the upper shell of the sensor.
Installing:
Installation is carried out in the reverse order. When installing observe the following:
  Caution
t  Prior to installation, thoroughly clean the surface of the windscreen inside the bracket for rain and light sensor -G397-. Any remains of coupling pad adhering to the windscreen must be completely removed.
t  The surface (coupling pad) of the rain and light sensor -G397- must not be soiled on installation. A sensor with damaged coupling pad must be renewed.
  Note
If the surface (coupling pad) of the rain and light sensor -G397- is soiled, it may be possible to clean it by „bonding on“ and then „pulling off“ one or more adhesive strips.
–  Clean windscreen within retaining plate thoroughly; cleansing agent → General body repairs, interior; Rep. gr.68.
–  Remove protective cap of new rain and light sensor -G397- if necessary.
