There are a couple on eBay from Lithuania, Poland and Germany. Also there is the Part number - 80A601027A, which is from the Q5 (FY) 2018 model, it has a ET24 offset so you would need to check it would fit first - listed
here. There is also another version part number - 8R0601025H, again I don't know if it fits on the hub or in the boot (subwoofer etc), you would need to check first - example listing
here.
