I've just done mine, It's a real git of a thing to do, Start by taking off the Air Filter Box & Tubes, now look underneath the light cluster, there is a small gap between the bottom of the light cluster & where the air filter box was. look through the gap & you will see the power steering cap, Mine was really tight but i did manage to get it off, once you get it off there is another cap inside which you can pop out with a screw driver. I also didnt have a funnel so i used an old A3 laminate that i had & rolled it into a funnel & then topped up. Hope this helps & good luck.
