If by whirring noise you mean what I think you do, my sister's 2018 PD i30 developed this when near new.
At the first service the dealership checked it out and the technician made a note that it was a noisy bearing in the steering column and it would be fixed under warranty.
The following day, my sister received an email from the dealership to say that it would not be covered under warranty because, and I quote, "they all do it."
Due to other (more important) things happening in her life at the time she didn't pursue it, but I thought the dealership response was poor to first acknowledge it was a fault and say it would be repaired and then say it's a fault but a common one so it won't be.
