Hi folks,
I was looking for advice I recently had my cam belts changed ,gearbox and transfer box oil change at 62000 I was wondering when I should look to get the diff oil changed.
As ever appreciate any advice.

Hi,
using the D4 2012 onwards service sheet, same as your RRS, the rear locking diff should be at year 5 or 80k miles which ever comes first and then at year 10 or 160k,
so
every 5 years is good and from memory the RRS has the locking diff (it was an option on the D4)

so worth doing

 Porsche Cayenne 2022
gone Porsche Cayenne 2020
gone Corris Grey HSE Dynamic 2016
gone Ipanema HSE lux 2010
gone Rimini HSE 2005
!!

Thanks for the info appreciated.

Changing oil can never do any harm, thought the locking diff was option on the Sport as well, only the pre-facelift factory HST had it fitted as standard, if you do have locking diff it is a different spec. oil used to the open diff as well. Never really worked out how they determine some of these intervals. Locking diff is larger capacity of oil as well.

Replaced my rear diff oil the other week, paperwork indicated it had never been done before and the car is at 72,000 miles.

When it drained it was still clear! Also not even a spot of metal on the drain plug, so I was very happy indeed.

As said above, it can never hurt to change the oils.
