Wondering if anyone ever had this code pop up. Proceeded to start the car Sat morning and as soon as I turned the ignition to accessory mode the CEL posed up with the following code. I have sport cats and this code doesn’t seem to be related to those. Car wasn’t driven for about two weeks and was on a trickle charger for about a week.

I had a similar issue but with a few more codes that appeared about a week later. Turns out that the dealer was able to identify a defective/faulty throttle body and replaced it under warranty. I've driven about 300 miles, and no more problems.

Here are a list of codes I had:
P2198, P2279, P013F, P0306, P0300, P0305

What they replaced under warranty is:
PAA-133-141 Throttle Valve Adapter
0PB-129-646-B Seal

​​​​​​​Note: I have a 2024 Porsche 911 Carrera T with a build date of Jan 18, 2024.

@zanary Thank you. This is very helpful. My 992 is a '21 C2S with about 28K miles. I cleared the code yesterday and will drive around today to see if it pops up again.
