Actually, you're in luck. First, CCV is likely going to be covered by the 15year/150k miles warranty by the dealer.

Second, even if you were to replace it yourself, CCV is a part of the valve cover on M56-- no need to spend 4-5 hrs contorting yourself to replace it or paying someone for that much labor as you would with M54. The cover itself sells online for about $470 brand new. This valve cover is made of aluminum and doesn't crack, and is actually easier to replace than the plastic valve cover on M54 due to easier access.

Third, there's only one short plastic hose involved going from the VC CCV to Intake. Pop it off and check if you see oil pooling there. To access that area, just pull up the black engine cover -- it's just friction-mounted with rubber grummets unlike on M54.

Check the picture in post #28 here. It shows where that hose connects
