strange buzzing noise under acceleration

Please watch video, been researching this noise. I'm thinking the waste gate is making this noise or the solenoid? Brought to two different ford dealers and no luck.

Anyone have any thoughts? Took a mini vacate this weekend and drove 2 hours each way and i can hear the rattle inside the cab when I'm either picking up speeds or slowing down off the exit

I'll be honest; as much as I would like to help you here, I really don't hear anything weird in your video. I'm not saying there's nothing wrong, just saying I can't hear anything. Any trouble codes or secondary symptoms linked to the noise you're hearing?

I have a CEL on for a def pump that is leaking and the light is registering a loss of pressure in the system, I'm not sure if the two would be related.

My only guess is that maybe you're hearing cavitation in the DEF pump. That's the only guess I have, good luck to ya!

Welcome to the forum, Snyder518. When you were at the dealership, were they able to replicate the noise? What's your truck's model year/mileage? I'll do a little digging and see what I can do to help.
