WARNING: This page does not describe the selected car, but rather 13 other vehicles, including the 2017 Audi SQ5, 2017 Audi Q5, 2016 Audi SQ5, 2016 Audi Q5, and 2015 Audi SQ5. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Following installation operations and with no hydraulic fluid in the expansion tank, the steering system must be checked for leaks.
-- Remove the noise insulation, refer to OVERVIEW - NOISE INSULATION .
-- Start the engine.
-- Turn steering wheel in both directions to full lock and hold briefly.
This builds up the maximum possible pressure.

In this position, the following components must be checked for leaks.
- Seal ring for steering pinion at the steering gear valve housing.

This test can only be performed with bellows slid back.

-- Push back the boot.
If fluid is visible in steering gear housing and/or in bellows, steering gear must be replaced.
