Conversation Between Emre@Esmotor and kenromero

Hello, have you experienced the error code P0021, cam problem, on the 997s you have modified? I've read a few owners have had the problem and pinning the cams seemed to solve it. I also heard that replacing the cams would sometimes solve it. How common is this problem? Does it happen only on the modified 997tt? If I haven't experienced it yet, do you believe it's only a matter of time? I have the engine out now and after reading the post by Yumaverick and his experience I'm thinking perhaps I should have my cams pinned while the engine is out. What is your advice?
Thanks for all the info you post on this forum, I wish you were in So. Cal. !!!
