OVERVIEW - VEHICLES WITHOUT DYNAMIC STEERING, Vehicles with 6-Cylinder Diesel Engine

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.

Power steering pump is not designed to be serviced. If there are customer complaints, the cause must be determined using a pressure and leak test. If there is a malfunction, replace the power steering pump.

NOTE:

If there is no fluid in the reservoir, then the steering system must always be checked for leaks.

If there are leaks in the area of the line connections, the lines/connections must first be inspected for leaks, tightened as necessary and wiped dry.

Power steering pump is delivered without oil. Therefore, Hydraulic Fluid must be filled before installation and turned by hand. Otherwise, noises when driving or damage to power steering pump may occur.
