WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2018 Porsche Cayenne, 2017 Porsche Cayenne, 2016 Porsche Cayenne, 2015 Porsche Cayenne, and 2014 Porsche Cayenne. However, it is still accessible from the selected car via links, so may be relevant.
Information
The following components of the steering system must also be replaced on all vehicles:
- Reservoir
- Suction hose from reservoir to hydraulic pump (referred to as "suction hose" in the text)
- Return line from steering fluid cooler to reservoir (referred to as "return line" in the text)
After replacing components, the steering system must be flushed with approx. 3 - 4 liters of steering fluid. This will flush impurities, resulting from defective components and/or wear, out of the steering system. A second mechanic is required for some of the repair work.
