Front and rear diff take 75w90; 0.8qt for the front, 1.1qt for the rear.

Transfer case take a specific fluid part number G 052 536 A2, 0.7qt.

Transmission fluid part number is G 055 540 A2, 6.3qt refill spec but IIRC when I did mine on my Touareg (same transmission) that spec is to account for overfill and you have to set the fluid level correctly by getting the trans up to temp via VCDS or IR temp gun and loosen the drain bolt with the engine on until all the excess fluid drains. I used Ravenol ATF-WS but you can easily use Toyota WS transmission fluid as it's easier to find and reasonably priced.

I used the Ravenol 75W- 140 GL5 for my 2015 Q5 transfer case, apparently VW ok'd and less cost that the OEM brand.

G052536A2 (Gear Oil) is OEM fluid for the transfer case
G052145S2 is OEM fluid for Diffs.
Ravenol TLS-LV is good alternative to OEM ATF, fraction of the cost.. it actually holds ~11qt but you can only get ~6qt out the drain, so do a couple changes 100 miles of eachother if you want to do a more complete change.. you end up using alot of ATF but your not paying OEM prices so its not that bad.

No, thats your transmission fluid.. transfer case is G052536A2.. there is no aftermarket equivalent afik.. you only need like one bottle, suck it up.. minus engine, you need 3 different types of oil to do a full drivetrain lube job.. Diff, Transfer Case, Transmission are all different.

Transfer case fluid

So it only takes 1 bottle for the transfer case????G052536A2 (Gear Oil) is OEM fluid for the transfer case... i already did the transmission filter and fluid change. Used febi atf and filter kit from ecstuning. I used redline 75w 90 in the front and rear differential.

~0.7L capacity of gear oil for transfer case, G052536A2 is 1L..

0.7 < 1

so it only takes 1 bottle of G052536A2 for the transfer case.. the very first reply to you contained all this information.
