Help,what power steering fluid?

[Stax]

2007 A4 B7 Avant 
Getting a bit confused on what p/s fluid is correct.
I bought the green synthetic MVCHF recommended for CH11S and CHF202 after reading on an Audi forum it was correct but the filler cap and reservoir on car are stamped mineral only?
Any help appreciated.

Thanks, I know it's obvious to use what is stamped on filler cap but I keep reading the synthetic I mentioned is what I need, someone on one of the forums went as far as to say just ignore the stamp, hence the confusion.

The car is a 2L diesel btw.

Thanks Jason, the whole story is that I had a new p/s hose fitted recently and the system isn't working properly, low revs and it's stiff more revs and it eases up. It's going back for a investigation as to whether the pump has gone. When I checked the fluid I thought it had a redish colour which was obviously put in when they did the hose.
