Keep us posted on your end results! The dealer does control the process so don't let them push you too hard.
Also if you are mechanically inclined these are not too horribly bad DIY jobs. I know on the x3 forums we have some solid write ups on our stickies for both the m54 and n52 inline six. I am sure similar postings are out there for your v8.
Also regarding oil changes I change mine every 8k miles with BMW 5w30 synthetic oil regardless of what the computer says. My 09 is at 103k miles and has no leaks and the lifters are as quite as a church mouse.
However I am a classic over maintainer. My end goal is 300k miles. For me it makes logical sense to do this. I promise I am NOT trying to start the 1,000,000 oil change debate thread.
