The wiper and washer functions in E46
vehicles are controlled by the ZKE V
general module (GM V). Driver input to
the system is via the multi-function
stalk switch to the right of the steering
column.
Operational faults in the wiper/washer
system will set Diagnostic Trouble
Codes (DTCs) which can be accessed
through BMW scan tools DIS or MoDiC.
The components of the wiper/washer
system are described below. Some
functions or components are optional,
as indicated.

has four wiper settings for the
