I had the same squeaking dash/a-pillar noise (not the hard rattle).... ended up being the hood. After adjustment on the hinges and front hood stops it was quiet. There's a TSB, but it does not completely solve the issue. It's not the hinges alone.
Bilstein are only expensive if you buy them from Aus suppliers! - if you buy them direct from the US they're MUCH cheaper - thats INCLUDING cost of freight!!!
Great video, thanks for the heads up! Do the Old Man Emu aftermarket shocks also have this noise if you know? For me, I had a noise but it was a slightly loose upper control arm bolt. Spec calls for 40ish ftlbs but I found if I don't tighten mine to 52 ftlbs, they make noise.
