970 4S transfer case service
New to me Panamera and new to this forum
not new to wrenching.
Im very surprised how hard it is to find service information for the transfer case.
Im not talking about the front (or rear) differential, and no not the PDK.
I had my car on a friends lift recently, and I wish I took better pictures. I was able to find the drain, but unable to locate the fill plug.
Any information or advice will be greatly appreciated, thank you.

Correct. That's where it is on the 971. I suspect you have the same thing.
The vent on mine has been spitting a bit so I've been draining and filling with each oil change to flush it. I really should just flood it with solvent to flush it, but I've been lazy and haven't ordered the fittings for it.
I use a small oil pump can to fill it. Capacity is tiny (less than half a liter).

transfer case/front differential
I am confused. The thread begins with: "Im not talking about the front (or rear) differential, and no
not the PDK."
I can't find any reference to a transfer case other than the front differential. Aren't they the same?

Thinking more about the response by TIC_Clint, I now realize that hes likely referring to the front differential.
I will need to look closer next time my car is on the lift. Im getting conflicting information regarding this vehicle and a transfer case. I am definitely not trying to circulate misinformation, quite the opposite.
I talked to a tech at FCP euro regarding this. I was told that yes, in fact, there is one and he sold me the plugs to drain and fill it. This was after he gave me all of the information regarding the front and rear differential, so I do not believe he confused them.
Definitely not suggesting they are the end all and be all, but Im trying to work with people that have more experience than myself.

That part comes up as used for a Macan or Cayenne transfer case
That said, I guess Ill assume there is not one unless I see a legitimate Porsche technical document stating otherwise Thank you for your guys help.
