Does the N55 have an oil cooler? If so I'll inspect it tomorrow if I can get to it.

looks like this is an oil cooler heat exchanger failure. The way it works is by interweaving oil and coolant so that they can exchange heat. When they fail, the oils mix with the coolant and vice versa. There is a least one for the X3 and 2 for models that did not come equipped with an oil cooler.
Look at item 9 for the most visible heat exchanger.
Look at item 1 for the heat exchanger that services the transmission.
