I don't know why, but this seems to be poor design. I also suspect that,
once the first leak occurs, the interface between the hose and fittings on
the oil filter cooler become progressively bad.

Two bits of advice:

1. It appears that the stuff accumulates on the fitting. If you simply
replace the hose, it will likely not seal correctly. That's why I used the
Dremel wire brush and ground down the solidified pink crud that was on the
fitting. I would not use anything much more aggressive, as it may gouge the
fittings and yield leaks.
2. At first I thought I had only one leaky hose, so I bought the
replacement from my Audi dealer. Hold on to your chair: it was USD22!. When
I got things apart and decided to replace the other hose as well, it was
Saturday and, of course, every Audi parts place on the planet was closed. I
went to my friendly "real" parts place (not one of the chains), passed the
other hose to the guy behind the counter and asked if he could find
something similar. After about five minutes of hunting around, he came back
with three choices. I picked the most promising one, paid him the USD9 and
left. With a cut in the right place, it worked fine. I used a little "Aqua
Lube" on the ends to get them to slide on and seal. Always use the stuff;
one tube lasts a lifetime.
