This part is listed by BMW as BMW part number 11377643073 (11 37 7 643 073) and is described as Genuine BMW Valvetronic Actuator for F22 M240i, F30 340i, G20 M340i, F32 440i, X3/X4/X5 40i, and G29 Z4 M40i.

This actuator is what actually moves the Valvetronic system on B58 and B58TU 6-cylinder engines. The actuator uses an internal sensor to determine piston, crankshaft, and camshaft positions and then moves the camshafts and valves based on instructions from the engine computer. It's a hugely important piece of engine operation. A failure of the internal sensor or the motor itself will throw a check engine light and may even stop engine function altogether. There should be a fault code for Valvetronic operation. Other symptoms include a loud, rapid clicking from the valve cover, and hunting idle and throttle hesitations.

This is a Genuine BMW Actuator 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.
