There is a DIY video on BavAuto that shows how to do it (older BMW but same procedure)

Now, CHF-11S is more expensive than the ATF most of my previous cars have used so depending on just what percentage of the system level is contained in the reservoir I might change that to "every second or third oil change" for my E90.
I agree with you. It makes sense to have a car with fresh fluid rather than wait till its too late and ruin your power steering pump. I think this process will help the life of the pump. I will definately add this task when I change my plugs in the next few days. Although I asked my friend the BMW tech yesterday and mentioned that according to his experience which is 15 yrs working for BMW, never change Power Steering fluid unless is leaking or requested but never for maintenance purposes. Not it makes me wonder if mine has ever been changed!!!

FYI the CHF 11s is only 21.00 for 1 liter at Napa Auto stores.
