[Sphinx15]

I searched in this forum and didn't find anything, perhaps this will help someone else. Seems like other X5/6 models have this issue. I had it as well, a "clunking" sound from the trunk at low speed over bumps and low speed turns/parking lot maneuvers. Stuff like that drives me crazy...

The solution for me was from this post over in F15 - I would also suspect adjustment/increasing the height of the trunk bump stops would work as well. A few wraps of electrical tape and I'm now rattle free.
