BMW Engine Oil Pump - OEG 11419895359

Modern cars use volumetric flow-controlled oil pumps. This means that the oil pump can vary output based on engine demand. This style of oil pump is used to improve engine efficiency by reducing parasitic drag on the engine. Conventional oil pumps produce the oil pressure necessary for the largest possible oil flow rate that can occur in the engine. In many operating situations, this represents unnecessary energy consumption through the oil pump and additional wear of the oil.

Volumetric flow-controlled oil pumps deliver only the oil necessary under preset engine operating conditions. No additional quantity of oil is delivered in low-load operating ranges, and this in turn reduces fuel consumption and oil wear and tear.

The oil pump, regardless of whether it is a standard or volumetric-based variant, can wear out over time. This is particularly the case in engines that have not been maintained properly.

Please note: Oil vacuum pump, old version with plastic adjusting ring: BMW part number 11 41 8 646 453. Oil vacuum pump, new version with adjusting ring made of sintered steel: BMW part number 11 41 9 895 359. G20, G22 / B58D / US / with optional equipment (OE) 033T - M-Technik package already have the oil vacuum pump with an adjusting ring made of sintered steel since series launch. If an oil pump/oil vacuum pump with an adjusting ring made of sintered steel is combined with the old DME data status (the I level is lower than 20-11-500), the oil pressure control is susceptible to vibration
