hi!
was thinking of changing the oils in the:
Differential 1,1L
Transfer box 0,5L
Rear differential 1,?L

have any of you changed the oils?
did you use anything else than Audi original?
brand?
specification on the oils?
(local dealer here in Sweden wants 100dollars for 1L Transferbox oil!...is it made of Gold? =O)
cheers!/H

I had the dealer change the transmission and differential fluids in my 05 4.2. I don't remember the cost but it dramatically improved the shifting of the car.

haha bye

Do you by any chance have the part numbers for the diff and tranny fluids?? I need to do thre change as well.

How many miles did you have on the car when you changed the fluids? Thanks.

KevinGary

I changed it between 35K and 40K miles. As I said, it made a significant improvement in shifting and the elimination of the Quattro low-speed-turn rumble. My car is now approaching 60K miles and its is still smooth. I will probably change it again at 80K miles.

haha bye

thanks a lot! you wouldnt happen to have the tranny fluid p/n too would you? Those p/n's you gave me are those for the right amount I need for the car or should I look that up in the manual?
Thanks!

Thanks!

the manual says nothing ..coz it's life-time oils they claim ..*L*
i can give you p/n nr...but there is 2 different Automatic tranny oils depending on the cars vin/chassies nr.....one yellow oil and one blue as i recall..one really expensive and the other less expensive)..best is to get Audi stock oil from dealer i guess...so you get the right one for your car/transmission software..or whatever determines the right oil..hmm
the trans/diff fluids are as i recall...0,5L for middle box..1.1L for front...and 1.5L for rear...this is for the 2005 Quattro tiptronic..
cheers/H

changed the oils and put the "cheaper" oil in middle diff/box....no good!
now i got the Quattro low-speed-turn rumble. =/
strange....since the A8 have this oil specified in Etka....oh well..
just bite the bullit and order the 100dollar/L oil....damn... =(

btw...oils in rear/front where pretty dirty looking..just for info...
