Trans/Diff Seal

[erict@cta.com (Eric Thorstenson)]

Anyone know the details of the problem with the trans/diff
seal on the automatics? I understand Audi issued a recall
for a change of fluid, but can you guys help with
  - What is the recommended fluid for the diff? It's a
    synthetic, right?
  - Should I change the ATF, just to be safe?
  - Has anyone changed the seal? Has Audi developed one
    that works?

Thoughts anyone?

Thanks,
