Power Steering Cooler Return Hose, BMW - E82 128i (-12/10), E9X 325i/328i/330i

This part is listed by BMW as BMW part number 32416774305 and is described as BMW Radiator Return Line, as used on E82/E88 1 Series and E90, E91, E92, and E93 3 Series (E9X chassis). This hose is used on the 6 cylinder models using the N52/N51 engine , which include the 2006 model 325i, 325xi, 330i, and 330xi, the 2007-2011 328i and 328xi sedan, the 2008-2013 328i and 328xi coupe/convertible, and the 2008-2013 E82/E88 1 Series 128i (non turbo models). 

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.
