Going by the style of the numbers moulded into the pictured caps , they look like Chinese copies, rather than German original caps.
If the part number you’ve quoted is the correct cap for your wheels then buying German ones is the only sure fire way of knowing they’ll fit, otherwise buying some more copies and gambling that they will fit might be worth it?
The Chinese copy caps (of all the various designs Audi do) are normally a fraction of the price of Genuine caps....
