I have
these which stick on, I got them a lot cheaper than this price tho. When pulling from the top you just need to make sure that you use two fingers or do not pull from the topmost tip else the stock Audi paddle pivots in a way that does not make contact with it's microswitch. Other than this I have had zero issues.
From your picture it would seem the left paddle is the same as the ones I purchased, and the one on the right seems to be a complete replacement. I would suggest searching for Golf VII ones and then seeing if there is an Audi version once you have found manufacturers / sellers, which is why I did.
