Oil pressure control valve

WARNING: This page does not describe the selected car, but rather 45 other vehicles, including the 2016 BMW M5, 2016 BMW 550i xDrive, 2016 BMW 550i, 2016 BMW 535i xDrive, and 2016 BMW 535i. However, it is still accessible from the selected car via links, so may be relevant.

The oil pressure regulating valve is a solenoid valve (3/2-way valve). The solenoid valve is seated in the crankcase at the side. The Digital Engine Electronics (DME) activate the oil pressure regulating valve by means of a pulse-modulated signal.

This enable more precise activation of the oil pump than via the volumetric flow.
