Help on changing differential oil in 2005 A6
I have 103K miles on my 2005 A6 Quattro 3.2L.
I changed out the rear differential oil which was quite dark with no issues,
am glad that I did change it. The oil I used is G 052 145 S2.
I know the front and center differential also takes the same oil.
I know that I have to change oil in the front and center differential, but
quite don't know how to do this as I think I found the inspection/filler plug but cannot locate the drain plug. If anyone has done, would be great if you had some pictures to show what has to be done.
My automatic transmission is 09L.
Thanks

I am a bit confused about center differential oil which as per your info it is ATF fluid. As per Audi Fluid Capacity Chart, it says that all differntial including rear, central and front use G 052 145 S2.
I already changed out the ATF fluid 2 months back.
I also called the Audi dealer and they said the same thing.

i believe, front center and read all use the same. i purchased them all in the dealer and they didnt to be any different.
im planning on doing the rear, since the front was done when they replaced the front diff and the center i have no idea where and how to access it.
good luck

Yes, HRC4U is correct.
Front and rear use the same oil G 052 145 S2
Middle one known as transfer case uses a different
oil G 055 145 A2.
The fluid capacity chart from Audi, surprisingly
has no mention of the transfer case using a
different oil other than G 052 145 S2.
I have only done the rear differential but will
do the front this weekend and then see if I can do
the transfer case oil.

How did you change out the middle one?
Did you have take out the transmission support?
I have a long small nylon tubing which is connected to a
hand pump to suck out oil. I use that suck out hot engine oil
in all my cars for the last 15 years with no problems.
Do you some pictures that you can post, that would be great.
This forum is so helpful, thank you so much!!!!!
