Power Steering Cooler Return Hose, Rein - E46 325xi/330xi

This part is listed by BMW as BMW part number 32416796680 and is described as BMW Radiator Return Line for the all wheel drive (AWD) equipped E46 3 Series. This includes the 325xi and 330xi "xDrive" models for the 2001, 2002, 2003, 2004, and 2005 model years. It also includes the 325xiT / 325xi Touring Wagon, also offered from 2001 to 2005. 

BMW has two hoses they call a Return Line - this one being the hose running from the power steering cooler to the reservoir. And on the xDrive "xi" models, this line is specific to the 325xi, 325xiT and 330xi. Its job is to 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.
