I have 2014 Cayenne Plat edition V6 3.6, I like to change diff fluid front and rear axle. My local Fletcher Jones porsche dealer looked up my vin and they provided the part # .
The front and rear differentials take the same fluid and the part number is 000-043-305-04. Did you use this part #?
I thought the part is 000 043 205 30 75W90.

Porsche is probably right with the part#. I just wondered about it.

Thank you for your feedback.

 

000-043-305-04 is a new part, replaced 000 043 205 30 75W90.
