  1. I'm going to respectfully disagree with JFP.  Numerous detailing professionals and us normal people use a pressure washer to wash cars. I suggest further reading at Detailers Domain, Ammo NYC, Adams Polishes for more information.


    I use an electric pressure washer for my gar. Gas versions may produce to much PSI and flow rate that can be an issue in car washing.

  2. I contacted Becker Service that builds the PCM's and discussed with them the issue with the incorrect/missing date. It is something they have seen on occasion and may be related to two possible issues.

    • CAN BUS communication issue with the Porsche Instrument cluster - This would need to be checked by using something like a PIWIS or Durametric or other code reader and verifying no codes are present. Clear/Fix any error codes and see if the date returns. If no errors then see next.
    • Corruption with the PCM software - They state the PCM is very sensitive to voltage spikes, low power, battery change etc especially as the units start to get older. Generally can be fixed by sending the unit in for repair.

    They told me a bench test is $75 and if nothing else is wrong other than the date the repair fee would be "reasonably less" than the usual $500-$750.

  3. Not sure which code scanner you have. Not all scanners can clear codes or its dependent on the model. Are you a PCA member? Maybe someone in the club has a Durametric Pro / Foxwell NT510/520 or similar setup that can try to clear the code for you. Definitely try to get the code cleared first and go from there. This is a known issue back to when the 997 was first sold.

    If we're stuck with the wrong date due to a GPS system change, can the date display on the PCM be turned off?



    My date is incorrect and does not display on the main PCM display now. The time and timezone are correct at least. I've tried different date formats too. If I have time I may run down to my local indy that has PIWIS and see if that helps the issue. Its a small annoyance.


    Porsche could do something about this as it appears to be a programming bug. There is a PCM update disk set being sold by a vendor and they have a 2015/2016 maps update. I may try that and see if that corrects the issue if nothing else fixes it.

  5. Yep - You are missing the date in the Main display. I called my local Pcar dealer but I got the usual bring it in and we can look into it - for a fee or course.


    Anyone have a PCNA contact as I think this is a weird problem (bug) , albeit small, in the grand scheme of things. Im hearing more people report this across other Porsche forums.

    I have a thread : in which I had a time issue also after batter replacement.  I think I figured it out - I actually always changed the clock in the dash when daylight savings came around.  after the time was messed up after battery change I also used the dash to reset and it was changing on me.  Messing around, I was reminded of the reset option in the PCM in which I then had the right time set but the GMT was wrong....  They noticed that the daylight savings was checked - after changing that and setting gmt to -6, alls well with the time.  BUT now my date is wrong - reads something like 03-12-2000.  So now I have a wrong date and dont see that it can be reset??




    Out of curiosity do you have a date displayed on the Main PCM screen or is it missing? Mine still says 01/09/2000 and is not on the Main screen any longer.

  7. This is being reported on other forums for the 997 and early Cayenne's and I'm in the same boat along with a coworker. The date display on the PCM is blank while all other settings are correct. Ive done the 1,4,8 reboot and pulled the fuses etc. I have 8-11 Sats locked in and the map follows me correctly. This just started a few days after the new year.


    I suspect there is a firmware bug in the PCM with the coming 2019 GPS Week Rollover. I wonder if a PCM Nav update to the latest SW & maps (2015/2016) works around this?

  8. I'm planning on doing this replacement with the excellent DIY documentation found here. However, my 997 is a Tip - is there anything significantly different in performing this from a MT before I get started? I have not found anything specific at this point other than the correct part # for Tip's



  9. I need a rebuild and their argument is persuasive on our 964 to go 3.8, or even 4.0 stroker rebuild? any experience w their interior and electronic work? Experience w timelines and estimate accurracy? We are on the East Coast - anyone of high rep in east rebuilding these cars?

    Advice appreciated?

    I would search all over other forums. Comments regarding MotorMeister are mostly not positive.
