For the cam follower, have you got m8 triple square bit? Assuming you have I found the best way on my old axx was to use a 1/4 ratchet, about 5 inches long, with a 2 inch extension + the m8 bit holder m8 bit. So from the ratchet to the end of the m8 bit is about 4-5 inches as well. Then go up undeneath and through the hoses/ fuel lines into the banjo bolt that way.
RE the DV bolts, they are allen key bolts IIRC. If you have a small torch you could strap with tape somewhere to aid visibility, also keep bonnet open for light. Make sure the bit is in the bolt securely before turning, as you dont want to round them off. I seem to remember 1 of 3 bolts being up and above the DV which makes it harder, but not too hard. Also i've assumed you have taken the wheel and arch liner off and gone through that way, as going from directly underneath would be a little more difficult.
