First of two questions: seepage in rear differential

I have some seepage in my rear differential, but my mechanic told me that it wasn't necessary a critical problem as long as I refilled the fluid level every now and then. What is the right kind of fluid to use, and where do I access the diff to put new fluid in?

fluid change on '97 A6q wagon? I was told by some goofball that there was a transmission, transfer case, and front and rear differentials. There is only a transmission and rear differential, correct? I can't see anything else.

...front final drive (front diff), and rear final drive (rear diff). So the goofball was right. All 3 use the same fluid, as in the post above. Capacities for the 100 (like mine) are center diff - 2.2 pts., front - 2.2 pts., rear - 3.6 pts., according to the info I have. I believe the A6 should be the same. Bentley says to fill to lower edge of filler hole (all three), and also says to drain and refill these units only is "absolutely" necessary. And get yourself a Bentley manual.
