2014 S3

Pleased to have found this forum.
I'm hoping it can be a useful source of info, plus perhaps I can help one day.
I've a 2014 S3 (55,000 miles) which has recently started making a 'humming' noise from the rear. It's regularly serviced.
My local garage (not Audi) has checked the wheel bearings, and they seem ok. Tyres look ok, no odd shapes in the profile. It's a strange one as the sound is louder as I free-wheel/roll forward, without accelaration, even at very low speeds 2-3-5mph, but as soon as I apply even the smallest amount of throttle the sound/humming reduces by 50-70%. I thought it was wheel bearings but at such low speeds it did seem a bit odd.
Any advice would be very much appreciated
