Power Steering Pump, Hydraulic Lines And Reservoir Overview, Vehicles Without Dynamic Steering [CALA]

WARNING: This page does not describe the selected car, but rather 19 other vehicles, including the 2017 Audi S5, 2017 Audi A5 Quattro, 2016 Audi S5, 2016 Audi A5 Quattro, and 2015 Audi S5. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

The 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 pump.

If power steering fluid is low in reservoir, check steering system 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 oil must be filled before installation and turned by hand. Otherwise, noises when driving or damage to power steering pump may occur.
