Guys,
Can someone tell me where the oil fill port is on Cayenne 958. I can't seem to find it. 958 doesnt have the fill port on the pan..it's somewhere on the driver's side of the tranny I read somewhere...

 

The fill port is located on the passenger side on top of the transmission. As I recall, it requires a hex head wrench to remove. A mirror will make locating it much easier. You can use a hand pump on the transmission fluid bottle to refill the transmission. Just be sure you replace exactly the amount that you remove.
Mine took about 6 liters.

 

Thanks! I used the drain port to fill per the workshop manual. Used garden sprayer and VAS6262/2 adapter. My car took about 5 liters cold fill.. I haven't found an infrared temperature reader to top off yet. I read that only PIWIS can read ATF temperature on 958..

 

I'm kinda late to the party but a Durametric will also show the temp. You may actually be overfilling without checking it at operating temp.

 

What ATF did you guys end up using in each of your fills?

 

Motul Multi ATF About 6.5 quarts.
