WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2018 Audi S8, 2018 Audi A8 Quattro, 2017 Audi S8, 2017 Audi A8 Quattro, and 2016 Audi S8. However, it is still accessible from the selected car via links, so may be relevant.

Procedure

NOTE:

If the windshield wiper motor is to be run during the work procedure, the hood must be closed. Otherwise, the voltage supply of the wiper motor will be interrupted.

-- Remove the windshield wiper arms. Refer to WINDSHIELD WIPER ARMS, REMOVING AND INSTALLING .

-- Turn on the ignition.

-- Activate "one-tap wiping" and let the wiper motor run into its end position.

NOTE:

Every second time the wiper motor is switched off, it returns the wiper arms to a slightly lower rest position, thus tipping the wiper blade lips the other way.

To do so, the windshield wiper motor moves the wiper arms farther down than to rest position and then a bit up again. This lower rest position must not be used to adjust the wiper crank.

Only use end position where wiper arms run directly into the end position with no understroke. Activate "One-touch wiping" again if necessary.

-- Turn off the ignition.

-- Position the wiper arm with wiper blade installed at the wiper axle.

-- Align the wiper blade tip -2- on the lower edge of the windshield -1- to the cowl panel trim -3- as follows:
