Coolant leak
E65/E66 N62 7 series V8's have coolant leaks tokidoki. We're replacing this silver coolant pipe in the middle of the engine or valley pan. It's also a good idea to replace the water pump o-rings and coolant pipes. This is a big job, maybe 30 hours or so because you have to remove the engine. I have no idea why BMW made such a bad design. It's a good thing warranty covers this.
