I have a 2017 SQ5 and suffer something similar when i'm driving on an uneven road at around at 30mph or less. Audi Poole technician heard the noise but they couldn't diagnose the problem. I've read on other forums that the disc rotors are the problem, but proving it is hard. I read that Audi Aberdeen had 4 or 5 cars with the same issue back in 2013/2014, all had rotors changed and the noises stopped.
