We own a 2015 RS4 and just need to confirm a couple of service items if any one has the information?
1. The rear diff = uses x2 types of oil (ATF AND GEAR) - don't think I have any questions on this part as its fairly simple inc VCDS prime.
2. Gear box (s- tronic) = has x2 filters and the process again looks ok, I believe this gearbox has 2 chambers for the gearbox?
3. Front diff = is this the drain and plug on driver side (uk spec) and is this the 2nd chamber to change oil like above on number 2?
4. Does this car have a transfer case and does it have a separate oil storage to change?
All info much appreciated, just want ALL fluids done and just trying to confirm if there is 4 or 5 points of changing of oil.
Also I know the b7 suffers with carbon build-up etc, I take it the b8.5 suffers with this too?
Regards.
