ask ur dealer to replace the middle row seat clamps..tht was the problem in my case after 3 weeks of finding it

Did you ever get this resolved? The shop has my 2007 (May build) 3.0 X5 now. They said they have tried to replace the Sway Bar and Upper Strut Mount and the rattle still exists.

I couldn't find a service bulletin as it appears to not be sticky any more relating to this. Basically looking to give them any pointers I can to get my car back, so any resolution notes you have would be greatly appreciated!

Thanks

had this issue recently and fixed...dealer noted caused by right front sway bar bracket bolts came loose....retorqued with locktite.
