All wheel drive controller oil?
Hi All,
I searched but could not find an answer about this. When Porsche is talking about the "all wheel drive controller oil" needing replaced at 6yr/60k I'm assuming they are talking about the transfer case fluid. However when I was looking at the 60k service procedures it appeared that it was describing the front diff oil. The front diff oil isn't supposed to be done until 12yr/120k according to the maintenance schedule though. Then I noticed it also refers to "all wheel final drive: change oil" on the 12yr/120k for 991's.
Can anyone confirm that the "all wheel drive controller" is the transfer case, and that the "all wheel final drive" is the front diff???
