just found this if its not too late. Audi dont seem to sell the figure 8 seal and some other seals between oil cooler and engine block.
The guys on Audiworld have of course found a way round this, a company that sells the seals separately.
May still be ok with the old seals though, mine didnt get the new seals either as Audi wouldnt sell them separately.

They sell the "8" seal alone.
Their site is a little odd to navigate, but if you got the part #'s it's easy...you just type em in on their home page. They got every odd part you can imagine for Audis.
077 115 441 ..."8" oil seal
077-117-411-A ... Water pipe
077-121-437 ... O-ring for metal and plastic pipe (x3)
I got all of em for about $40, including shipping."
