Cayenne Turbo S (9PA) V8-4.5L Turbo (2006)
Power Steering Pump: Service and Repair
Removing and installing hydraulic pump (Cayenne Turbo/Cayenne S)
Damage to the power steering will occur if there is a shortage of oil in the hydraulic system. Even small leaks can cause the hydraulic fluid to escape
and damage the servo pump as a result of high oil pressure occurring in the hydraulic circuit.
Grunt-like noises that can be heard when the steering is locked, or foam formation in the reservoir indicate a shortage of oil and/or that air has also
been sucked in. Before filling the reservoir, any existing leaks must be eliminated on the suction side. Alternatively, the defective part on the pressure
side should be replaced.
Increased risk of accident and material damage if too much Pentosin CHF 11 S is filled in or if Pentosin CHF 11 S comes into contact with
the coolant hoses when filling or topping up.
Overfilling of the system with consequent overflow of Pentosin CHF 11 S onto coolant hoses and other components may occur.
Before inspecting the fluid level, run the engine for approximately 20 seconds. Multiple steering operations (maneuvering) will alter the
fluid level in the reservoir! Check the fluid level.
If coolant hoses come into contact with Pentosin, thoroughly clean them with water IMMEDIATELY.
Replace visibly swollen coolant hoses.
