Two weeks ago it has changed to 22/2/2000 and I can't change it even despite a trip to RPM Technik who tried to flash it using a PWIZ tablet.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

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.

9 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

Hi All Can anyone please help with how to change the date on the PCM 2.0 in my 996 Turbo S Cabriolet MY 2005. Two weeks ago it has changed to 22/2/2000 and I can't change it even despite a trip to RPM Technik who tried to flash it using a PWIZ tablet. I know it is just a date but my OCD brain goes mad seeing it. Rang Porsche at Silverstone who said they haven't come across it which I find hard to believe considering the number of posts here? Have tried all the suggestions and really thought the PWIZ flash would have worked. Any suggestions please to help me sleep again at night lol!?? Cheers Webbo

POST 2Original post

There has been a number of questions on this of late .. ive listed it on several posts . Basically you can't or rather you can't unless throwing a lot of money at it on software updates they may not work . The latest software update doesn't fix it .. it just hides the date from the main screen . My understanding of it .. there was a GPS roll over in April and any device over 10 years old will have trouble .. The cars all work fine until a flat battery or a disconnected battery at which point they revert to year 2000 with a few different months listed .. ie 1.7.2000 is common . http://911uk.com/viewtopic.php?t=135446

POST 3Original post

can't fix...google GPS rollover. Mine has done the same (as many others have, if you have had battery disconnected after april this year, it will be back to 2000). TIme for a decent radio...

POST 4Original post

I noticed mine had done it about 6 weeks ago,very annoying, my batterys not been flat!!

POST 5Original post

I wonder if we all complained would Porsche do something about it?

POST 6 / ORIGINAL POSTEROriginal post

Hi All Thanks for all your help and is really annoying as I hate things not working as they should do lol. Likewise my battery has not been disconnected so that can't be the only reason? I assume it also happens on other models e.g. 997s ? Maybe some Porsche Member Guru will find the answer! Cheers Webbo :nooo:

POST 7Original post

Not a hope in hell I suggest. Dr Mr Porsche, Can you please bring out some new firmware for the system which you discontinued 15 years ago to fix a rather minor annoyance I have with it. Yours Owner of old car MC

POST 8Original post

Re: How to change the Date on PCM 2.0 Porsche 996 TurboS MY It happens on 997 as well . As per my link .. ( 997 forum ) .. i did find an answer .. it's expensive and you can't lock the car for about 3 weeks !! It will also only last until the next flat battery . I'll just add .. sometimes with a low voltage battery then on cranking the voltage falls low enough to trigger this fault so its not set in stone it's a flat battery .. a starter motor drawing too high a current will also cause the same fault . Porsche are not interested in any car that's no longer in production .. regardless of what they advertise .

POST 9Original post

Does anyone have access to the firmware source code? If it was made public I'm sure it could be fixed
