I have a 2000 A4 5 speed quattro 2.8 v6 and I'm going to Wyoming for 6 months. I'm going to do some basic maintiance on her before I leave just for peace of mind. My question is, is there a central differential that would need the fluid changed or is it just the front and rear? Ive search all over the place but havent had any clear answers. So just a run down... I'm changing the front tranny & rear differental fluid along with the engine oil. I have to change a CV boot also but thats pretty straight forward.
I am very good with cars but this is my first Audi and first AWD car.


Thanks for any help

 

No separate center differential. You have the front differential, which is inside the transmission and shares fluid with the transmission, and the rear differential. When you refill the transmission fluid to the correct amount the front diff should be all taken care of.

 

On your manual transmission(01A) the center diff(torsen) shares the fluid with the rest of the transmission which also includes the front diff.

 

what about on a 06 2.0t automatic? where can i find the refill plug?
