BMW Power Steering Hose diagram for 545i, 550i, 645Ci, 650i

The power steering pressure hose is a high-pressure line that connects the power steering pump to the steering gear or rack. It carries pressurized power steering fluid from the pump to the steering mechanism, allowing for easier steering by amplifying the force exerted by the driver on the steering wheel.

• Fluid Leaks: A common sign of failure is visible leaking of power steering fluid around the pressure hose or its connections. This can appear as puddles or wet spots under the vehicle
• Increased Steering Effort: If the pressure hose is damaged or obstructed, it may result in reduced fluid flow to the steering gear, making it more difficult to turn the steering wheel
• Unusual Noises: Whining, groaning, or hissing sounds may occur when turning the steering wheel, indicating air in the system due to a leak or that the pump is working harder than usual

About Genuine BMW

The original parts used by BMW to build your car are available as replacement parts under the “Genuine BMW” brand. When ordering a Genuine BMW part you are guaranteed to get the same part that you would pick up from your local dealerships part department. Genuine BMW parts have been built to BMW’s stringent standards and are the same quality of the original parts used to build your Ultimate Driving Machine.

You may not realize this, but the parts that make up your BMW are not necessarily manufactured by BMW. No cause for concern, as BMW designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for BMW for decades. In our industry these manufacturers are called OEM (Original Equipment Manufacturers), and these are often brands you recognize, including Lemforder, ZF, Sachs, Bosch, Valeo, Zimmermann, Siemens VDO, Corteco, and more. Don’t be surprised to open that Genuine BMW parts box and find an OEM branded part inside, simply with the addition of a BMW logo.

Be sure to keep an eye out for OE tags on our product pages to quickly identify parts coming direct from OE manufacturers. That extra bit of insight could save you some serious money while shopping! Refer to our OE Academy for further information regarding the OE/OEM tags throughout the site.
