question about s-tronic parts
 

hello everyone,

i have recently purchased used 2011 A6 3.0 TDI Quattro 245HP (7 speed S-tronic) and i wish to do a complete service of the transmissions (s-tronic filters and both oils (ATF and hypoid)) as well as check the oil status in the differentials, just to be sure in case it hasn't been changed recently. i'm trying to avoid the official dealer since they are overcharging and as far as i can tell they only change the ATF.

this is a procedure that i can do myself, however i'm having doubts regarding the correct choice of filters and oils (contradicting information on the internet and the service manual isn't clear at all). i would be very grateful if someone can point me to the correct part numbers for the filters and oils based on the car VIN number (WAUZZZ4G0BN016789).

i am also having doubts whether the rear differential uses only hypoid (75W-90) oil, or there is also ATF there as well?

thanks upfront!
