Need Help: RPM Rattling Noise

I'm hoping someone can help me out with this. Recently I noticed a rattling noise when my vehicle goes from 1000 RPM to 2000 RPM. It only happens the second it up shifts from that range. Has anyone had this issue before? I got a 2014 F30 xDrive around 85K KM. I brought it to the dealership around February and they told me it was my exhaust flap, however now the problem is back.

Maybe a heat shield? Where does it originate from? Do you hear the rattling when the car is in neutral and between 1k-2k RPM? I'd say take it back since they're already aware of the issue.

The noise comes from underneath the car. It only happens when the car is going forward and shifting from 1000 RPM to 2000 RPM.
