BMW has two hoses they call a Return Line - this is the hose running from the power steering cooler to the reservoir. It returns fluid back to the reservoir. Like the Inlet/Supply Hose it has non-reusable crimped hose clamps where the hose meets the reservoir. Leaks are very common here as the clamps loosen and the rubber hose swells.
This is a power steering hose manufactured by Rein (CRP) Automotive - an original supplier to BMW for many engine components. As an OEM, Rein meets all of BMW's original design, fitment, and performance requirements and is TUV approved. OEM parts are the best alternative to more expensive Original BMW parts because they are virtually identical without the inflated price tag. This part has a two year warranty.
