Hi, amc, it looks like I have the same car as yours 2006 X5 4.4i, what did you have to remove to gain access to the alternator from underneath? It looks like I can remove a few hoses, but the alternator sits directly above some metal frames which are hard to remove. Removing those hose only gives you room from the front of the alternator, not directly below, it's still hard to reach the alternator...Thanks much.
