Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

My 2012 997.2 won't let me set the date, and the date is wrong (it shows 2007), although I can set the time.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

My 2012 997.2 won't let me set the date, and the date is wrong (it shows 2007), although I can set the time. From what I've read, if the car has GPS, the PCM only takes the date from GPS — and because of the GPS week rollover bug ( https://safran-navigation-timing.com/the-gps-2019-week-rollover-what-you-need-to-know/ ), the date comes out wrong. I've seen a video where someone switches the PCM to a non-GPS mode, which then allows setting the date manually ( https://www.youtube.com/watch?v=futlmJweU3I ). But that video is for a Cayenne, and when I plug into PIWIS 2, the options aren't the same for the 997. Has anyone tried this on a 997.2?

POST 2Original post

I wouldn't bother trying to defeat the GPS module electrically. On the 997/PCM 3.x, go into PIWIS and manually code the PCM Navigation option to “W/O Navigation.” Recode it, and the normal Date & Time menu should then allow manual date entry. Set the correct date, then go back into PIWIS and restore the original navigation coding. Btw, PIWIS 3 appears to expose the relevant coding more clearly than PIWIS 2, so if the option genuinely isn't present in your PIWIS 2 software, borrowing/renting access to PIWIS 3 may be the easiest route.
