clearly shows the coolant lines attached to the (N55) turbo.

Now, you're right about the M57 turbo, but wrong for the vast majority of folks reading this thread.

This is very interesting and I'm happy to stand corrected. The link doesn't make it clear whether that's water or oil feeds, but it certainly seems too big for oil. In particular, my protection of turbo comments relate (made unclearly) about the bearings. They MUST be being fed by oil to lubricate and cool. What info is available on that? I can't believe they are ceramic besrings which require, as I understand it, less 'care'.
