Windshield Wiper Arms, Adjusting

WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2015 Audi Q7, 2014 Audi Q7, 2013 Audi Q7, 2012 Audi Q7, and 2011 Audi Q7. 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 wiper arms, refer to WINDSHIELD WIPER ARM, REMOVING AND INSTALLING .

-- Turn on the ignition.

-- Activate "one-touch wiping" and let wiper motor run to 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 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 end position with no understroke. Activate "one-touch wiping" again if necessary.

-- Turn off the ignition.

-- Position wiper arm with wiper blade installed at wiper axles and align wiper blade at windshield as follows:
