I'm having a hard time trig to figure out what rear differential fluid my 2013 CTT takes.  It has the PTV electronic rear end on it and from what I understand it has carbon fiber discs in it and requires a specific fluid.  Anyone have any sources that provide a brand/part number?

Cool.  I was able to cross this over to Ravenol MDL.  The Porsche part number floating around was 000 043 300 37.

It took about the 1.3L to fill it.  The chattering at low speeds it was experiencing is all but completely gone.  This is very similar to the transfer case oil changeout I did a little while ago.  I'm at a bit over 55k miles.  The old fluid was like black water coming out of there.  So this will also be something I probably change out every 30k miles moving forward.

It's amazing to me that Porsche basically tells you to never change the driveline fluids.. with active clutches in the transfer case and the torque-vectoring rear diff - its certain that the fluid will deteriorate - due to sheering from the clutch, and material worn from the clutch.  WHAT are they thinking?
