PPI Help!!!
I'm in the market for a new 957 and found the one I want. A PPI was performed and 8 fault codes were detected. While reading through report, I'm finding more than 8 fault code issues, maybe it's the way I'm reading it. Can someone help me read all the fault codes? Should I be concerned by these codes? What should I glean from this information? Are the faults going to be costly? I've included the overspeed data as well.
The PPI did list that the battery is weak at 11.4 volts standing after charge while inspection performed. Thanks for any and all help

I think the general advice on here is that when the Cayenne starts throwing lots of errors, you check the battery and then the cables in the footwell.
In this case if the battery is reading low, that would suggest it's the source of the issues. But that's not guaranteed.
What is the asking price? Every Cayenne, no matter it's issues is a good buy at the right price.

What are the total # of operating hours in the DME abd what's the vehicle mileage?
I'm surprised to see range 3 and 4 overrevs in a Cayenne that has an automatic transmission, but it looks like at 3,182 hours someone really had their foot in it, right up through the Rev limiter. I bet that was recent too, like on a test drive. Any chance the car has an aftermarket tune that would have raised or eliminated the Rev limiter?
Until that KESSY error can be cleared and stay away, proceed very carefully. There are chips in the steering column that when they fail completely brick the vehicle requiring it to be disassembled and the chips mauled off for repair or a new steering column for multi-thoudands of dollars.
As Nelak mentions though, multiple strange error codes from unrelated modules is often a bad or weak battery. One test is with the car not running, to try and open the power hatch a few times in a row. If the battery is weak, the hatch will get stuck part of the way up. This will happen when there's still enough power to start the car.

Vehicle is a six-spd manual, not an automatic. Does that change the reaction to ranges 3/4 overrevs?
Spoke with the seller yesterday and the battery was being replaced and new diagnostics ran. It should clear any obscure issues related to a low battery. Seller mentioned that it was still on the original Porsche battery from when the car was originally purchased.

Total number of hours from DME shows 3629 with current mileage just shy of 100k.

Is it a GTS, S, or base model - just curious.
I'm pretty sure your error code issues are a weak battery, especially now that you say it's the original. I had to change my original battery in 2016 (mine's an 09). They seem to last longer than normal 5 year lifespan of most batteries being protected the way they are under the driver's seat.
If the new battery resolves the error codes and the rest of the PPI checked out, I don't see anything here that would keep you from moving forward with the purchase.

The error codes are good in a way...you are assured the seller is not trying to conceal issues by deleting them.
I have hit the rev limiter when I first acquired my GTS. It did not reoccur when I discovered that it's OK to skip 1st gear.
Just be certain the clutch is not slipping.
And yes that battery is way overdue for replacement.

Be mindful too, if you replace the battery, you need to drive it the 50 miles or so to let the sensor's reset and then see if the CEL and DTC trip again.
