Volvo V40 D2 2014 Oil filter location

Apparently Haynes aren't even planning to do a manual for this, Anyway, here is my first problem. I decided to change the oil, which was easy enough, and (while I was at it) change the filter. I expected it to be underneath somewhere, but the only thing that looks remotely likely is actually on top. There seems to be a black cap some 3" in diameter with a hex head on it near the top right hand end. Trouble is - I think I'll need to remove a water hose to get at it, which I'd rather not do until I was sure I'm looking at the right thing. Can anyone here confirm the location for me?
