WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2024 Audi SQ5, 2024 Audi Q5 e, 2024 Audi Q5, 2023 Audi SQ5, and 2023 Audi Q5 e. However, it is still accessible from the selected car via links, so may be relevant.

Procedure

TIP:

If the windshield wiper motor is to be run during the procedure, the front lid must be completely closed, otherwise the power supply to the wiper motor will be interrupted.

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

-- Switch the ignition on.

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

TIP:

Every second time the windshield wiper motor is switched off, it returns to a lower rest position, which ensures that the lip of the wiper blade is turned in the opposite direction.
To do so, the windshield wiper motor moves downward past the end position and then goes back up again slightly. This lower rest position must not be used to align the windshield wiper crank.
Only use the end position where the windshield wiper motor runs directly into the end position with no under-stroke. If necessary, activate "one-touch wiping" again.

-- Switch off the ignition.

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