This part is listed by BMW as BMW part number 11157623745 (11 15 7 623 745) and is described as the vent outlet hose from the valve cover to the turbocharger duct on B46 engines used in F22 / G42 230i, F30 / G20 330i, F32 / G22 430i, G30 530i, G01 X3 30i, G02 X4 30i, and G29 Z4 30i. This covers both B46A and B46D engines. This hose has an electrical connection for a small heater circuit that prevents the oil vapor and droplets from turning into a sludge in cold climates (aka Blow-by Heater).

The crankcase vent system is responsible for separating oil from the air inside the engine and air intake. Liquid oil is returned to the oil pan while oil vapors are sent to the intake (via the turbo) to be burned up during the combustion cycle. It's also known as a a PCV, CCV, and oil separator system. Too much oil in the intake air lowers the effective fuel octane, leads to drivability issues, and causes increased emissions. A completely blocked CCV has the potential for very serious engine failure (hydrolock) if liquid oil ends up in the turbo or intake. Signs of a failing CCV include: whistling noises in the intake, blueish smoke in the exhaust, high oil consumption, and thick white or yellow gunk under the oil cap.

This is a Genuine BMW B46 CCV hose with a two year warranty. Buying a Genuine part will usually be more expensive than an OEM or aftermarket brand but you are assured that it meets BMW's designs for fitment, performance, and longevity. It will also be the very latest design, incorporating any updates or revisions that an aftermarket brand typically will ignore.
