Overview - Hydraulic Line, Reservoir, 6-Cylinder TFSI, With Dynamic Steering

WARNING: This page does not describe the selected car, but rather 18 other vehicles, including the 2016 Audi S4, 2016 Audi A4 Quattro, 2016 Audi A4, 2015 Audi S4, and 2015 Audi A4 Quattro. However, it is still accessible from the selected car via links, so may be relevant.

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 power steering pump.

NOTE:

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.

The power steering pump is delivered without oil. Before installing, fill pump with Hydraulic Fluid and turn pump by hand. Otherwise, the power steering pump may be noisy when operating or may even be damaged.
