I have a 2009 Accord 2.0 petrol with MT and there is some sort of a whistling/whining noise (like a turbo or a supercharger) coming from the engine bay when I press the gas pedal in 1st and 2nd gear. The noise seems to change/disappear when I press the clutch to change gear, but it reappears when I hit the gas. My local dealer says everything is fine with the engine and that I should live with the sound. I went for a second opinion and the answer was similar. They all say 'it's the way it is'. Since I bought the car secondhand, I don't know whether the sound has been present from the start. Opinions?
