Its difficult to hear if its the same noiwe on this, but cool video.0:32, 2:35, 3:10, 3:37, 3:50, 4:00 (probably the longest duration). You should be able to hear the induction noise whining over the air and engine noises.
That being said, its much louder in the cabin because you don't have the sound of air that's also being picked up.
The noise I canāt unheard basically happens if you are driving normally and back off from 2,000 rpm. It sounds like youve just drank the last of a milkshake with a straw.
Itās annoying as it only happens in normal driving, Id prefer to have noise in sport mode and back to oem in normal.
