V6 TDI Engine
Power Steering Pump, Hydraulic Pipes and Reservoir Overview
Vane 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 vane pump.
• If the power steering fluid is low in the reservoir, check the 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.
• Pump is delivered without oil. Therefore, hydraulic oil must be filled before installation and turned by hand. Otherwise, noises when driving or damage to pump may occur.
