Engine noise on acceleration

Hey all, so I have a 2014 N63tu, when I press on the accelerator I get a weird noise that seems to come directly in front of me in the engine bay (driver's side). Once I let off the gas there's a second delay and the noise stops. It's hard to tell exactly what it sounds like, sort of like an air leak with with a hint of a metallic noise. The dealer replaced both turbo inlet tubes and gaskets since there was some play and an independent mechanic suspected an air leak there, but the sound remains.

I was told if the noise was from a pulley that it would make it all the time and not just under acceleration, but that's honestly what the noise sounds like most.

I'm going to bring it back to the independent mechanic to run a smoke test, but does anyone have any idea what they think it could be to help localize the inspection?

Thanks in advance.

Hello from Spain,

Did you find out what produced the noise?. I have the same problem. In my case, the noise only appears between more or less 125 and 145 km/h and like you, only under acceleration.
I have visited three dealers and none have a clue. I would have to leave the car a few days in the dealer to let them investigate. So it would be great if you know what was the problem.
Maybe it's a different problem but luckily it's the same.
Thanks in advance

I'll try, but I'm not sure you'll can hear it well. Thanks
