This is the fluid cooler used in the power steering system. BMW calls it a radiator. The cooler runs fluid from the steering rack back to the reservoir and is exposed to airflow to cool the fluid. Leaks here are uncommon unless the pipes have been damaged by debris or corrosion.
This part is manufactured by an aftermarket supplier of European auto parts, including many steering and suspension components. While not carrying OEM status, this part follows the design of the original very closely and uses similar materials. An aftermarket part may even have the same TUV approval as its OEM counterpart. The brand may even be OEM to another manufacturer besides BMW. This aftermarket brand has a two year warranty - the same as Genuine BMW and OEM brands
