No idea.

However, there is a factory supplied instruction sheet somewhere on this board with detailed pics of what the dealer does if you bring it in.

If you are a DIY'er it's worth a shot to try yourself.

FYI, my hatch was perfectly fine until I messed with my latch. It now has a minor squeak when going over bumps. I loosened the latch bolts to mess with it out of curiosity, actually I thought the latch should be more solid, but it really shouldn't be rigid and it isn't on brand new showroom cars. Anyway, I haven't gotten around to messing with it more to see if I can fix it.

A lot of folks with older X5's complained of a squeak that came from the bottom hatch flap. I had my flap replaced ~6months ago and BMW put in a updated flap that uses beefier plastic and the felt part that rubs against the lower hatch and was/is the source of noise for many people was also upgraded with beefier felt. I'm just assuming that all the LCI models have this new and improved version.
