WARNING: This page is about a different variant/trim than selected.

Special tools and workshop equipment required

Vehicle Diagnostic Tester

The windshield wiper system is equipped with the Alternating Park Position (APP) function.

The APP function causes the wiper at every second shut off to move upward slightly after reaching the lowest position.

To install the motor crank on the wiper motor, it is necessary to shut off the motor in the lowest park position. This is attained by deactivating the APP function (code Wiper Motor Control Module -J400-).

Note the following:

An activation of APP function is not possible.

APP function is automatically activated after 100 wiping cycles. This applies to wiper motors in which the APP function was deactivated as well as for new wiper motors.
