Modified behaviour of the rain sensor
Possible causes of faults and mistaken read-
ings on the sensitive surface
rain sensor include:
Damaged wipers: a film of water on the
●
damaged blades may lengthen the activa-
tion time, reduce the washing intervals or re-
sult in a fast and continuous wipe.
Insects: insects on the sensor may trigger
●
the windscreen wiper.
Salt on the road: in winter, salt spread on
●
the roads may cause an excessively long
wipe when the windscreen is almost dry.
Dirt: dry dust, wax, coating on glass (Lotus
●
effect) or traces of detergent (car wash) may
reduce the effectiveness of the rain sensor or
make it react more slowly, later or not at all.
Windscreen crack: the impact of a stone
●
will trigger a single wipe cycle with the rain
sensor on. Next the rain sensor detects the re-
duction in the sensitive surface area and
adapts accordingly. The behaviour of the
sensor will vary with the size of the damage
caused by the stone.
WARNING
The rain sensor may not detect enough rain
to switch on the wipers.
If necessary, switch on the wipers man-
●
ually when water on the windscreen ob-
structs visibility.
