Loud CLUNK noise from passanger side dash area

[Kris@modmynav]

Hello,

I've had this clunk noise for awhile, dealer tried to fix it but no luck.
it's coming from passanger side dash area when I hit the bump at low speed.
I went to dealershop and few independent shops to check my control arms and sway bar links, but everyone said they are fine.
noise coming from upper dash, not from the bottom, sounds like loosen bolt or nut.
does anyone have same or similar issue?
oh btw, I've lowered my X5 before with H&R and Eibach springs but I have stock Sports package springs now.

Thanks for any tips.
