S3 Whine when holding high revs

Hello,

Got a 59 plate s3 sportback and have noticed that when rolling and holding revs at about 4k there is a fairly loud sort of whine. It vanishes when you bury the go pedal and is not apparant when accelerating normally. Question is, is this normal?

Typically when in second say holding back behind a slow moving vehicle waiting for the chance to overtake.

Thanks for the tip, I'll have a look there. Its all standard atm.

I would say its more of a transmission whine to be honest when she's on overrun. Pulls like a train and the noise isn't apparant at all when not holding the revs under any sort of acceleration. Only noticed it a couple of times, will have to reproduce it and see if I can identify the likely source better myself.

I didn't get any noise like this with my mk5 GTI, but despite the similarities the way the car behaves is a lot more different that I was expecting so maybe its not the benchmark I thought it would be. I was just expecting same but faster / grippier but there is more to it than that.
