Q5 2018 Q5 quattro/rear diff service

[grainqey]

Hello,
I've been on here for a while and recently made a jump in an FY Q5.

I wondered when the rear diff should be serviced? I'd have said 60k miles for a conventional rear diff is overkill but ok if trying to look after it.

Is the quattro decoupling service taken care of with the s-tronic gearbox service or is it like the haldex rear diffs that have two seperate oils for the clutch portion and actual diff portion?
Thanks in advance

Hi mate,

From what I believe Audi class the rear diff as a lifetime fluid. I've asked a few garages and they have recommended getting it done before 100k. Good video below. May be completely different for non S variant.
