When doing a project like this I must rely on the parts catalog sometimes......and every once and a while the part numbers are not correct. I NEVER trust the pics because Audi recycles pictures for other "similar" models. I was sure when I saw the part that it was not right. I had placed the correct rubber grommet on the reservoir before I had ordered this "securing pin" so thanks for the responses and reaffirming my belief.

Now it is "Item 31" (not "29") and, by luck, I had correctly guessed the PN involved, i.e. not 431129668A but 431129669, "grommet".
