Rain and light detector sensor G397
Location
The rain and light detector sensor is located in the
Golf Plus in such a way that it is positioned as high as
possible, centrally, in the wiping overlap range of
both wiper arms.
Task
The rain and light detector sensor only operates in
automatic mode if the wiper lever is set to the
"intermittent" position for rain detection and the light
switch is set to the "automatic headlight control"
position for light detection. The rain and light detector
sensor then ensures, when rain is detected on the
windscreen, that the wipers are actuated from zero to
the maximum number of wiper cycles according to the
quantity of precipitation, and that the headlights are
switched on in twilight conditions.
The rain and light detector sensor independently
adapts to the windshield's tinting.
At wiper lever level 1, in which the wipers operate at a
speed of 42 cycles per minute without rain sensing,
the wiper speed can be independently increased up
to 60 cycles per minute with rain sensing, depending
on the quantity of precipitation.
In the case of wiper operation without rain sensing,
this value corresponds to level 2. In level 2, rain detec-
tion has no influence on the wiper speed. In this case,
the wipers operate at a constant 60 cycles per minute.
The intermittent wiper regulator can be used to
individually set the sensitivity of the rain detector.
In vehicles without a rain detector, the regulator is
used to set the length of the intervals.
