I posted more details in the personal build thread.
Basically, we had a noise that would resonate around 2200 rpm. We thought it was the exhaust hangers: welds, since I had my exhaust in my old X3 m40 I was replaced. Not the problem
The we figured out that there was a plastic hose (something related to the fuel line/ tank) that would create a vibration.
First attempt was felt tape. It muffled it but wouldn't go away.
The final fix was spray foam. It made it go away and I stopped caring.
