Rack and pinion, power box, and power rack steering.
Im aware of 2 they are known as ball and nut steering used in older models and the most common type is rack and pinion steering which is most cars today....
Depends on the year of your BMW, and the style of power steering rack. There are 2 common types: 1) Electronic Power Steering (EPS) 2) Hydraulic Power Steering (HPS). EPS does not require fluid and HPS does require fluid.

It is not possible to alter a car from a manual steering into a power steering car. The engines for the two types of cars are very different.
two types I am aware of are rack and pinion and gearbox.
ball joints are common on most steering system and provide a controllable link to the other steering components.

Electronic power steering (EPS) and hydraulic power steering (HPS). Electronic does not require power steering fluid and hydraulic does, based on your owners manual power steering fluid suggested type.

A pretty common cause of this is that the u-joints in the steering column need to be replaced.
In order of MY observations: connections, hoses, power steering pump and finally rack or steering gear, although rack is becomming much more common.
