Seems like you may have skipped some steps prior to this. The filter is located inside a canister for which, as I understand from previous threads, you need a 13 mm wrench to open the canister, which is accessible from the top.
The rest of your instructions seem complicated, especially since I was given a pleated filter insert with a "O" ring seal. Oddly enough, the part number of the pleated filter is 11 42 7 509 208 compared with the number labelled on the box which is (correctly) 11 42 7 512 446.
Something isn't right here.
