Whats wrong with my car

[Aiden Bennett (AideB)]

On cold start i hear this sound. When i watch the revs they match the sound, go up and down with the pitch of the sound. Also hear a similar whining noise when car is accelerating, its not a dramatic sound but increases in pitch again with revs. I feel like its from the top of the engine where I can hear the whining potentially the turbo at the back ?

Always a good idea to include your car's age, mileage and engine code when posting.

Edit:- oh and trans.

Hard to say, sounds like an electrical motor or something from the clip.
