"Engine control fault, consult a workshop, driving permitted" - ok to track it?

The prospect of needing to have the car dragged out of my garage stuck in the park position in order to have it towed to the dealer for a simple ECU reset was scary indeed. Thank goodness all it took was a $50 scanner to get the car back in working order. Note to self: remember to connect the ECU BEFORE you start up the car...

1. Oil supply
2. Improper heat treat of the cam. Depth and surface hardness.
3. Surface texture on the cam
4. Higher than expected contact pressure on the cam
Consider that these are low production cars. Not sure how many cams the supplier can batch process. It could easily be 50.

Received the car back with a new 2016 engine. Related to your thoughts above, the 16s have a new oil filter. This suggests that there may have been a some tweeking of the oil supply and it might be the root cause of my problem. Thankfully Porsche took care of everything seamlessly for me. Another break in period...darn.
Thanks.

Interested too. Sounds like it could just be an oil filter brand/design change. They would definitely not change an engine oiling system during series production (other than to recall every engine as they did before). My guess is it's a different flow design filter which perhaps they feel works better. Pure speculation. The Latest pET will show any part number changes...

I just had my oil changed for the second time last week, 5000 mi. I'll ask my parts person if they know anything about a new for 2016 oil filter.

Stopped in to talk with my tech to clarify this. He said it is definitely different, but appears to have the same part number, which puzzled me. Finally having the SharkWerks center delete bypass put on next week and I will have him take a photo for me when that is being done.

Hey Ya'll - Just wanted to give a little update to the engine fault I've had ongoing the last few weeks. I broke down and took it to the dealer about 10 days ago and they were concerned with bad fuel (however, they did not take a sample), the code they came up with pointed towards the thermal management system of the car (mechanic said potentially a thermostat). After clearing the code, car ran fine with no issues. Mechanic said he did not see a reason to replace thermostat since the code could not be replicated. At that point, I asked them to change the oil (car has about 1800mi on it). Picked it up and all was well. Car was driving great and a day later the same fault re-appeared. Similar to the 1st time, I could notice a performance decrease even though the light did not say "reduced performace mode, etc".
Car is now back at the dealership and a thermostat has been ordered. Code was 2181. They tell me they are also sending a fuel sample...
Hoping this resolves the issue.

The fact that you're seeing a " Reduced engine performance " has something to do with the way the computer controlled system works in most modern cars. In order to comply with the strict regulations,most modern engines need to run at a very specific operating temperature. The mechanical side of the thermostat is designed to remain stuck open in case of failure to avoid engine overheating. If the computer sees that the engine is running at a lower than optimal operating temperature,it will set that specific code along the " Reduced engine performance " ,because the engine will be running too rich.

The P2181 is associated with the cooling system as a generic OBD2 code,but since most modern thermostats have an electrical side of the system,the computer will identify a problem much sooner and set a specific code. Since Porsche has had a problem with the supplier of some of the thermostat assemblies lately,I would suspect this is the issue in your case as well.

I just got my oil changed, and mentioned to the shop that there may be an updated oil filter. They checked into it and didn't see anything related to an update, but are using what they believe to be the correct filter for a '15 car.

Well, I was forced to test out the durametric on the car yesterday. The car threw a code as I was just cruising to a friend's house at 30mph.
Durametric connects and partially works, but it won't give me an exact read on the code and it would not clear it either
I used generic obd2 scanner and got p2181. The scanner couldn't reset the code either.
P2181 seems to relate to the cooling system. The temps are reading normal, though. I've had a light trigger once telling me the coolant temp sensor failed, but it disappeared on its own.
I disconnected the battery overnight and now the code is gone. Took the car for a drive and it runs fine with coolant temps normal. No repeat light either.

Dealer couldn't find anything and reset it. So far, no recurrence over a couple hours of driving in high ambient heat.
