Slight whistling/whining noise at low speed

[Wonka]

I’ve noticed a slight whistling/whining noise from the car. To be honest I think it’s just a ‘normal’ noise but thought I’d raise it anyway. 

I only hear it at low speeds (and low revs) when I accelerate a bit. If I moved off just using the clutch there would be no noise, but if I apply a bit of throttle I can hear it. 

Anyone had anything similar?

I have something similar: 

whistling sound when pressing the accelerator.

 

Same sound both in gear or neutral. 

 

It seems to be coming from within the cabin (I cannot hear it when opening the engine).

 

I have a Skoda octavia 2016 TSI/CNG stick shift. 

 

Any ideas what it could be?

Another 'slight noise at speed thread' a bit lower down .

Low motorway hum at low revs

Thanks. But this is not a hum. It is more like a low whistle. Only when pressing the accelerator.
