Hi,
What could be the issue, when driving it has whistle sound when accelerating, however it has no such sound when accelerating in neutral. I'm attaching video you might hear the sound,

Audi A5 2.0 TFSI Quattro 2011

Sounds like the air box personally, but then again it could be a loose seal, check in the engine area for loose fitted jubilee clips or even signs of cracked pipes ?
