[peter]

Hi, im needing to change my power steering fluid but I'm not sure if i have the right one
I bought
OEM power steering fluid for bmw, Mercedes Audi Volvo Porsche. The container is purple.

My car says CHF only. The one i bought says its compatible with

Is this the right one?

That's the same stuff I've been using for a couple of years now. It's made by Recochem, and is the 'proper' green colour.

As a side note (and in case you're thinking of replacing your anti-freeze), the 'OEM' branded BMW coolant is a light yellow in colour, so when I replaced mine, I went with the Zerex G48 ('proper' blue colour) formula. I don't think colour really matters, as long as the formulation is correct...I went this way for consistency.
Hope that helps.

Be real sure it's compatible with Pentosin CHF 11.S . It's not worth taking the chance as Pentosin is not compatible with other fluids. Could be an expensive problem. While you're doing it, good time to change the P/S reservoir. Not an expensive part and there's a non-serviceable filter in there that should be changed.

Replacing the reservoir is also a good opportunity to purge the old hydraulic fluid.

Install the new reservoir but don't connect the return line, connect the return line to a bucket or container to catch the old fluid. Add new fluid to the reservoir and turn the steering wheel from lock to lock. That will pump the new fluid through the steering system and push the old fluid out the return line. When fresh fluid starts to flow out you can connect the return line properly to the reservoir and top off your P/S fluid.

Mike Miller on PS fluid (and, yikes, I need to change mine!):

All 2006-on BMWs except the 2006 E46 require Pentosin CHF 11.S special hydraulic oil in the power steering system. These cars all have a sticker on the top of the power steering fluid reservoir cap setting forth whether they require Pentosin CHF 11.S.

Do not screw this up, or you will be in a world of hurt. Pentosin CHF 11.S is not compatible with ATF or any other lubricant or hydraulic oil!

If your car uses ATF in the power steering system, Red Line D4 ATF is fine if you want to use a premium product. I don’t recommend Red Line Synthetic Power Steering Fluid for use in BMWs.

The fluid mentioned by the OP meets the specs for CHF 11S, CHF 7.1, and CHF 202.
