This part is listed by BMW as BMW part number 11518671654 (11 51 8 671 654) and is described as the auxiliary electric water pump for the turbocharger cooling circuit on F22 M240i, F3X 340i/440i, G30 540i, G12 740i, X3/X4 M40i, and X5/X6/X7 40i models. This pump is for the turbo cooling circuit but is actually mounted above and behind the oil filter housing on the left side of the engine.

The B58A turbo cooling has a complicated layout. The pump and hoses are on the left side (intake side) and mounted to the oil filter housing. It pulls coolant from the turbo around the back of the engine block to the oil filter housing. Coolant is fed from the right side of the engine block (which is the cool side in the B58 layout).

This is an OEM aux water pump manufactured by Bosch - the original supplier to BMW for this part, as well as many other components. As the OEM it meets all of BMW's original design, fitment, and performance requirements and is TUV approved. OEM parts are the best alternative to more expensive Original BMW parts because they are virtually identical without the inflated price tag. This part has a two year warranty.
