    Clock Loosing Time

    Has anybody else on this forum has a problem with their clock not keeping good time? My 997S looses about 1.25 minutes per week. I took it for service and was told that they put in a request about it to Porsche. A reply came the next day that Porsche was aware of the problem and working on a TSB for it. Anyway, I just thought I would pass it along in case someone else has noticed the problem on their car.

    It's because the 911 is so fast that you actually go back in time...you should be glad, it means that you'll live a bit longer

    Re: Clock Loosing Time

    It's a known problem. In fact, my clock goes backward in time. Quite often, I start the car and the clock goes backward by one minute. For $100K, you would have thought that the Porsche engineers could make a digital clock that works.

    Hummmmmmmm... .

    Does your car have navigation module?

    If so it is embarassing that the clock display isn't coupled with the GPS thus exhibiting the absolute correct time all the time.


    Where's the "Excellence" in that?




    This would be yet *another* de-excellence-ification of the PCM unit.

    No NAV here. Sport Chrono & Bose are the only electronic options on my car. The tech at the dealership seemed to think it had something to do with a specific combo of options.

    Re: Clock Loosing Time

    Same here. I think the problem with the clock running slow on the PCM unit is because it is originally design for Navi function connecting along with a GPS unit. GPS gets automatic time re-calibrated when it is connected with the sat. So, when you don't have the Navi activated, the time is not accurate too. Any thoguhts about this???

    That's possible as I don't have the GPS and my clock doesn't work right. But I still go back to my original statement. For $100K, the stiking clock should work right.

    At my dealer's they say it's a problem related with no nav -cars.
    There is no solution at this moment... Mine is allready loosing time since it's first week, last year

    The solution seems to be to get the nav module. Sorry, just trying to be informative AND entertaining.

    Actually, I got nav basically so more of the dozens of PCM buttons would work. I soon realized that having the nav unit is kinda fun. It almost has become a "must have" in my book.

    Re: Clock Loosing Time

    Doesn't happen if you have the navigation system. It even chages on its own from standard time to daylight savings time. One more advantage of having GPS. But, having said that, it is horrible on a car as expensive as a Porsche that they can't put in a clock that keeps accurate time.

    Re: Clock Loosing Time

    I might be way out of date but here goes anyway:

    It used to be that quartz "movements" and their electronics on the chip were impossible to mfgr consistently just right. They just made a huge number of them and then quality controlled exactingly and expected to discard a large percentage of them for being too innaccurate for a particular client's tolerances.

    The discard pile: that's where all those cheap clocks and wristwatches come from.

    Sadly it seems some of these chips may have made it into our cars.

    Just a guess on my part... .

    I don't think that is the issue. All quartz movements are quite accurate. You can buy quartz clock movements that are guaranteed to be accurate to within 1-2 minutes per year for $5.25 on the internet. If you buy in quantity you can get them for a little as $3.10 each.

    Hard to guess what Porsche is using.

    Re: Clock Loosing Time

    I wonder if this seemingly non-fixable problem would make my car eligible for replacement under Kentucky's "lemon law". If so, then I could insist upon a free nav module...or they could give me back the $100 K I spent on the car. (Note: All of this should be read using a rather high level of sarcasm.)

    Maybe the TSB to correct the defect is that everyone get Nav retofit for free.
