05 Cooper S automatic. Why does the owners handbook have to make fluids such a big mystery. They don't even show it existing in the handbook. What is an over the counter substitute? This probably isn't the correct forum but that's another mystery to find too. Thanks for any help!

CHF 11S is for the Mini power steering, it is different to other power steering fluids

You should be able to buy a bottle at the MINI dealer.
You can also get it from a VW/Audi dealer
Probably also BMW and several others as well.
Pentosin makes CHF 11S fluid for your power steering,
which I've seen at some Auto Supply stores.
Don't use non-CHF 11S power steering fluid or ATF.

1 litre of CHF-11S cost £12.34 + vat at my local BMW dealer.
