(w/videos now!) Hunting down noises on acceleration from stop

Interesting problem here… sometimes I am getting a weird rattling noise when leaving from a dead stop that sounds like marbles in a metal can for about 1-2 seconds and then it goes away. It doesn’t always happen and all my inspections under the car haven’t revealed anything yet. Exhaust system seems tight, oil pump chain was tightened on Sunday, nothing appears loose.

It may happen more in comfort mode than sport+ and I don’t think it’s wastegate rattle (stock DPs).

I do have a metallic rattle on cold starts that seems to come front the transmission area, but it does not sound like this main problem.

Thoughts?
