I've been out of drag racing/car repair etc. circles for nearly 15 years now, and also totally unfamiliar with BMW's and most of the interconnected electronic modules used since 2000. I've been lucky so far fixing my present vehicles (all GM, from '98-'09, excepting the '01 X5) due to some past experiences working on similar, along with friends. The BMW X5 is like a puzzle box to me, in comparison.

Without a circle of friends/suppliers/race shops that helped me back in the 1990-2008 period, I'm basically on my own fixing my vehicles; the unknown complexities within the X5 are far beyond my comfort zone. And I completely distrust stealerships. So, I'm gonna compile a list of a new parts sources, parts manufacturers, and also independent garages that people can trust, just so I can deal with my X5, while I'm winding-down my car fetish, as I grow older.
