SOURCE: power steering fluid or ATF
Yes There Is ONLY ONE PLACE for Power Steering Fluid.
ZF Gemmer Steering
The ZF Gemmer steering is permanently filled with oil. There is no drain plug.
ZF Rack and Pinion Steering Without Power Assist
The ZF rack and pinion steering is lubricated for its service life and therefore does not require servicing.
In case of repair, steering components on E21 vehicles are to be lubricated with a sodium-based grease, with a temperature range of -30°C to +75°C .
Calypsol D 4024 BMW Part No.32 11 1 116 929
Ball and Nut or Rack and Pinion Power Steering
Only reputable brand Automatic Transmission Fluid (ATF) of Dexron® III formulation may be used for the power steering and power steering pump.
In case of brief hydraulic noise after starting at low outside temperatures, we recommend replacing the red ATF with green CHF or LHM oil (see below).
ZF Ball and Nut Power Steering with H31 System
The approved oils for BMW models with power steering and the H31 brake booster system are identical with those oils approved for power steering without the H31 system except for the following:
E32 models with self-leveling rear suspension and mutual oil supply tank in the engine compartment.
Countries with very low outside temperatures (e.g. Canada) had their power steering systems filled at the factory with Pentosin CHF 7.1 since 9/87 through 9/91. This is also to be used on vehicles built before 9/87.
Since 9/91, vehicles now use Pentosin CHF 11S instead of CHF 7.1.
Pentosin CHF 7.1 BMW Part No.81 22 1 468 879
Pentosin CHF 11S BMW Part No.82 11 1 468 041
These cars are marked with a pertinent label located close to the oil tank.
LHM oils (green color) of the following manufacturers may also be used instead of Pentosin (CHF 7.1):
The mixing of CHF, LHM oils and ATF is not permitted.
Pentosin CHF 4548 was used on vehicles built before 9/87 but is no longer available. However, mixing of Pentosin CHF 7.1 with residual quantities of Pentosin CHF 4548 are permiffed in these earlier vehicles. Mixing of these two oils is not permitted for E32/E38 vehicles.
The hydraulic system for power steering and power-assisted brakes must be drained as completely as possible when changing from one type of oil to the other.
All oil supply reservoirs are marked with the type of oil being used - ATF or CHF.

Here is your answer that should help. I personally do not care why you want to don this, it is your business, if you wanted my opinion on that, I feel you would of asked. Here is the answer you wanted however.
Hello Sir. Usually it would say in the owners Hand book you got with car? explaining all the controls functions of the car or 4x4? alternatively if you look under bonnet there only be four filling reservoirs: engine coolant water, washer bottle, brake Fluid,power steering. usually the engine coolant will be a largish cap about 2-3 ins either blue or black its NOT this one. The brake fluid Will be at the back of engine bay and so NOT his one. Washer bottle again will be a cap blue in color its NOT this one. the one you want should be near front of car /engine and should have a steering wheel symbol on it the caps usually smaller then the engine coolant and black attached to a small reservoir and when you remove it will have a dipstick attached to it or small spike attached to cap this is used to measure power steering fluid, hope this helps... Thanks Mike

when looking at the engine with the hood up, look to the right hand side for something that looks like this (#1 in the pic): http://www.realoem.com/bmw/showparts.do?model=ET37&mospid=47720&btnr=32_0957&hg=32&fg=20
it will be black in color, but don't confuse it with the oil filter housing. power steering reservoir will have a unique cap (#2 in the pic) that can be removed with your hand. the one that has the large nut on top is the oil filter. remove the cap and put in the correct fluid.
hope this helped.

There is a tank under the hood with a STEERING WHEEL icon on it. DON"T OVERFILL and use only PENTOSIN
