A few months ago on a road trip, I had an issue with my 992 C4S where I experienced loss of power / knocking and then a slew of check engine lights. After checking codes on the side of the road, I discovered I was getting cylinder 1 and 2 misfires. Car was towed in for service and had new injectors / fuel rail installed.
However - today I got a message from my service advisor that they have received an interesting new bulletin (attached) from PCNA. He states that they are now advised to do nothing and call PCNA immediately to send in a field rep to investigate any 992 with fuel injector problems.
Could this be the precursor to a larger recall for the 992? Thoughts? Should I contact PCNA myself knowing I had this issue?
Based on experience I think it is more likely that they have noticed these very expensive and intrusive warranty claims and want to see if a software flash will fix them like it probably has when tested in their own lab with injectors that were replaced under warranty. This almost always happens before any progression to a defect driven recall if a potential software/calibration fix exists.

That sounds like a rock solid theory. Good thinking!
In the past (1980's) poor detergent additive packages in gasoline caused no end of headaches for automotive manufacturers that used Port Fuel Injectors as opposed to Throttle Body Injectors or Carburetors that were in common use at that time. This ultimately caused manufacturers to identify those gasoline brands that were "acceptable" and by omission those that were unacceptable. Many Technical Service Bulletins and other means of public announcements followed.
Eventually a "Standard" additive package was accepted industry wide. Presently when this additive package is used, the gasoline retailer is allowed to state that their fuel is "Top Tier".
I wouldn't be surprised if PNA is not just interested in collecting the Fuel Injectors from an engine so afflicted with the failures noted by the OP. I would imagine that a fuel sample and an oil sample from the engine (as the vehicle arrived at the dealership) would probably be desired.

A apărut deja de 4 ori, am programat mașina la dealer, au schimbat 3 injectoare, de fiecare dată câte un injector, cilindrii 5, 6 și 1, odată ce au actualizat computerul motorului. Totul în garanție. Totuși, mă deranjează că mașina este mai mult la dealer decât la mine.
Din ce am văzut aici sunt probleme cu injectoarele....de ce nu vrea Porsche să rezolve asta

This is disappointing. Does replacement of the injectors require removal of the engine? How long do they hold the car each time you take it in?

Nope; only need to drop the rear fender. My 2023 GTS threw a cel last week with rough idle and reduced power. I immediately pulled over and had it flatbedded to the dealership. Codes indicated misfires on 2/4/6. The regional service manager was immediately involved and told my SA to replace all three injectors. I was really skeptical that 3 injectors would simultaneously fail thinking it would be the ECU or harness. Wrong. They replaced all 3 and if anything it’s running better than before.
Last time 35 days...on average about three weeks...until the diagnosis is made, until the part is ordered and until it is installed.
So far I have managed without disassembling the engine...since for certain cylinders you cannot change the injector before disassembling the engine.
It is frustrating.
Reason I use Sea Foam regularly in engine oil and gas tank on all my vehicles including my diesel bobcat
siberian
granted each case can be different, but my injectors had 7500 miles on them and were not dirty or blocked. Three going bad at the same time on one side is a defect and, at least according to my SA, it is not completely uncommon. Also, I had wondered if they need to completely drop the engine to replace and the answer is no.
I rarely floor my 2021 992 but a few times I did I got the reduced power message. The thing is the warning would go away and I thought it was just a sensor or something and didn't really care. Now my car is out of warranty and was wondering if t hey will have to change injectors to fix it will it cost me ? What an idiot for not taking it earlier to the shop for that reason. I don't think I even mentioned it when I did the oil changes
I take it you don't have access to PIWIS and didn't run a DTC scan at anytime. Too late to worry about what could have been done then, add a can of Sea Foam to engine and oil when tank is full to clean out the system should it not be a hardware issue like faulty injector vs crap and see if it happens again. Also keep track of where you buy your gas...
