Also known as a crankcase pressure regulating valve

Your BMW's crankcase breather valve is used to purge oil vapor from the crankcase to the intake manifold where it can be burned by the engine. This component has a known issue with freezing in cold environments if the engine does not reach operating temperature. Common signs of a failure include howling noises and oil leaks.

We also recommend replacing the valve cover gasket when installing a new oil separator.
