I had this code show up on my scanner as well. Symptom would include lazy engagement in cold weather from reverse to drive. Sometimes the torque converter would not lock up when going back on accelerator after light braking.
Just flushed the transmission this past weekend and discovered the factory fill low. Had to fill 1.5qt more than volume drained to get the "stream to drip" at 36C at the bottom of the gearbox pan before plugging. Will continue to drive it and see if the problem goes away.

Usually it is the control module that causes the problem. Based on all my study, the correct control module is 7P0927601A.
but then when I actually found the control module in my 2016 Cayenne S E-Hybrid, the actual number on the part was 09D927601.
My module was located by removing passenger tire well, where it was bolted right behind the back of the tire, which is basically under passenger floor/wall beneath glove box.
But if yours is the model 7P0927601A then everyone says it is under passenger seat. I looked there first before finding it behind tire well.
The error code usually is because connections are not great or part itself is bad.
Bought replacement on ebay but have not replaced yet.
If yours is same as mine then connector has weird locking mechanism. That locking mechanism needs to be pulled down from verticle position to horizontal position. It will be hard to do but a screwdriver placed in space just below locking mechanism may offer leverage to break it free, just be gentle as you can. But make sure locking mechanism is pulled all the way down 90 degrees before removing connector. But that connector type is probably only for my part # 09D927601 behind tire.
But I really wish I could find that computer thingy that hooks up to the car to change auto start stop code from 1 to 0 to turn off the function. Cannot remember what that computer is called.
some other ways to temp shut of auto start stop are unplug brake sensor above brake pedal, remove 12v battery sensor from battery, attach trailer light tester to put into tow mode, lift hood - start vehicle - close hood. But most of these methods will show errors on dash. So I have abandoned all of them. There is no button or accessible setting in my hybrid. Trust me I've looked for months.
Some say you can disable stop start by putting into sport mode but this is not true in my Cayenne.
Good luck and let me if you fixed the problem because I still need to solve mine.

Hi Guys,
it is an older topic but hope to get some help.
i have the same dilemma right now and wanted to replace the auxiliary pump controller.
How did you remove the "Getriebesteuerung" part below the seat? The first big controller once you remove the carpet.
Not really sure i can get it out and don't want to break anything.
Thanks,
Smiler

Well, I get to join the P0C2D club. I am also getting the P0700 CEL on our 2012 CTT. I'm positive they are both related. I can clear the CEL but when I shut the car off then restart I get a check engine light immediately along with the start/stop disabled message.
It appears the P0C2D is the culprit. Has anyone actually found the root cause of this? What did you do to fix it? I'm going to pull the passenger seat tomorrow and check the module connection.
