Changes to the functioning of the rain 
sensor 
Possible causes  for faults  and misinterpretations 
concerning  the sensitive surface~ Fig. 90 of the 
rain  sensor  include: 
• Damaged  wiper blades:  a film of water  or 
smears  caused by damaged  wiper blades 
can in
crease  the length of time  for which  the wipers are 
switched  on, shorten  the length of the intervals be
tween  wipes, or cause  the wipers  to run continu
ously. 
• Insects:  insects hitting the surface  can cause 
the wipers  to be  activated. 
•  Salt deposits : in winter,  salt deposits  can cause 
the wiper  to continue  to wipe  the windscreen when 
it is  almost  dry. 
•  Soiling : dry dust,  wax, windscreen  coatings (lo· 
tus effect) or detergent  deposits (automatic car 
wash) can cause  the rain  sensor  to become less 
sensitive  and react  too slowly or even  not at all. 
•  Crack 
in the windscreen : when  the windscree~ 
is impacted by  a stone,  a wash  cycle is triggered If ....
