Default tiptronic differential oil change

I want to change the gear oil in my 95 tiptronic differential, but I haven't found much in the way of instructions. I am looking at PET illustration 320-03, and it looks like #19 in the illustration is the drain plug, but I'm not sure where to put the oil in. I am going to try to attach the illustration. Is the plug at #35 the fill plug and is #19 right for the drain?

Thanks for the help. That picture doesn't look excactly like where I was expecting to find the fill plug, but I'm terrible with exploded diagrams. Now all I have to do is get under the car and I'm sure I'll find it.

Post script.
One of the reasons I was trying to find it on the PET was to order a fresh sealing ring for when I do the change. Do you happen to know the part number for the sealing ring for the filler plug and the drain plug?

The part number for the seal is 900.123.104.30

One tip (pardon the pun) to finding part numbers is to check in the 964 section of PET. Porsche will sometimes omit part numbers that are carried over from previous models. Hope this helps.

Same sealing rings as crank case drain bolt and oil tank bolt.
