When I pulled the car from storage in May, after sitting all winter, the car threw a P0017 code and went limp. The dealership replaced an OCV, a cam timing gear (which was physically broken), the ECU, did an oil change and gave it back. A quarter mile later the P0018 code. I turned around and took it back to the dealership. A second OCV, cam timing gear (which was also physically broken), another ECU, and a total of 3 weeks in the shop and all seemed well. (Techline's theory is that the car came from the factory with the broken cam sprockets, the ECU learned the original timing that way, and so it ran fine. When the car sat for the winter, sediment from the oil got picked-up when I started the car and the codes started revealing the broken sprockets).
After driving for a week with the stock tune and no codes I flashed the auto generated Stage-1 file. All was fine for a month, then the P000A. Flashed the latest v2.067, still P000A. Re-flashed the stock file, drove it for a week, got a P000C "pending" no CEL and took it to the dealership. By the time I got it to the dealership the pending code was gone. They drove it 150 miles over the next 2 weeks but no code.
Techline's position is that if there is no code, there is no problem. They don't care if I can't mod my car like everybody else. Since Subaru will no longer spend time and resources figuring out why the car is out of spec, I thought I'd reach out to Shiv to see if it could be corrected in the tune so the car doesn't go limp. So while I agree that this is very likely a electro-mechanical issue, I don't really have any other avenue. I'm reaching out to the community to see if anyone else has experienced this, or can figure a way around. Sorry for the long read, but this has been a bitch of a problem.

unfortunately CEL codes P000A/B/C are not defined in the definitions so cannot currently be disabled in the tune rom.

Someone would have to trawl the ECU microcode instructions to find them.

It probably not something you would want to disable anyway as faulty cam sprockets can cause oil pressure loss in some cases which can result in engine damage.
