But it's easily a $7,000 job when all is said and done. Right now, I'm thinking "GOOD FUCKING SHIT DANIEL" for getting the extended warranty through my Credit Union. Whewwww.
Not bashing! But this is unbelievably rare. It is in no way a "common" problem. No need to get crazy paranoid just yet.

The "common" problem for oil in the coolant in these cars is a degraded OFH gasket. They fail (although usually first with external oil leaks) in many N55/N54/N52 engines. Head gasket problems are almost never reported, even in very highly tuned engines. Why is it that BMW can design such a fine head gasket and fail in such an epic fashion with oil pan, valve cover and OFH gaskets? IDK
