This hose is required when fitting the updated engine valve cover on bank 1 (cylinders 1-4) on E60 545i, E63/E64 645Ci E65/E66 745i, 745Li, and E53 X5 4.4i, 4.8is. BMW made a change to the valve cover and crankcase vent in in the 2007 model year, so this fits cars made after that date or earlier cars that are updating to the newer design.
The updated N62 valve cover does not have the hole for the early-style vent/hose, and required the use of this updated original-BMW replacement hose/vent assembly.
This part is listed by BMW as BMW part number 11617563476 (11-61-7-563-476) and is described as Genuine BMW Vent Hose with Pressure Control Valve.
