I did this on my N54 yesterday. You have to take off or at minimum loosen the intakes manifold to get to the last screw.

I did not drain coolant, I just shoved a rag in the hole as soon as I removed it.

Also, did anyone who has done this on the n54 replace their manifold gaskets? Dealer sold me those gaskets as well but I didn't swap them out...
