  1. My car is a 2004 CayenneS (US model). 

     

    I bought the Durametric Software hoping that I can perform some basic engine diagnostic.  Not so true!

    Watching some of the postings on youtube to what you can do with Durametric was so cool but when it comes to mine, it ain't so.

     I want to do some "output" test, for example, turning on/off the coolant fan, sec fans, blower, etc...  the software for my model car will not support such test as I was told by Durametric Rep.! Bummer! 

    Of course there are other ways to test all the components I mentioned above but that was not my point.  Oh well, now I have a Durametric which just read/reset the fault code like a $35 generic code reader!  

    Am I the unlucky one?

     

     

     

  2. My car is 2004 S.  The batteries (2) were replaced in 2013 by Porsche dealer.  I am now experiencing weird electronic problems .  As I recalled it from the past, weak battery contributes to weird  electronic problems, plus, the batteries are 5 years old, Its safe to planning replacing the battery(2)!  And here's my thinking, can I replace and use only 1 battery with a higher capacity rating? or am I stuck with 2 batteries? can I swap front and back battery?  I don't think my model year has any kind of battery registration feature like many later BMW cars does it? Any advice is greatly appreciated.  Many thanks.

  3. Spoke too soon.

    After a long commute, the CE came back as code P2189 - this is where it all began....  Well, I know now that the booster brake vacuum is somewhat fixed (need to order the OEM tube).  I changed Gas cap, Oil cap and one of the device (solenoid?) shown on 1 of my photos.  I swapped the MAP air sensor (Right/Left).  I bought a vacuum tester - which pipe should I check for the vacuum leaks? or is not the vacuum? O2 sensors? new MAP sensors?   $$$$$ will go out the window!  The car drives fine - idle smooth...

     

  4. There is no CE at this time. I'm using iCarsoft i960 OBDII scanner.  There is a menu called "Diagnostic" (different from the usual Actron reader), there is a submenu called DTCs.  I select to read DTCs codes and P0102 came up.  I select to clear the code.  Restart the engine, no more PSM light.  Drove around the block for  10 minutes - everything feels/looks normal.

     

    Tomorrow, Monday, the commute will be 45 minute/30 miles.  I'll give updates.

     

     

  5. Lewisweller,

     

    Thanks to you, all codes are cleared.  I have driven the car for 15 minutes - no codes.  However, the PSM was on after my procedure of disconnect /reconnect the battery and it remains ON.  The brakes feel fine and of course I was able to stop the car.

     

    I'm going to search for PSM troubleshoot... I'll be back.

     

    Thank you so much Lewisweller

  6. I was troubleshooting code P2189, undo some vacuum line to test for leaks ... this is a different issue all together.  I mentioned it because I unhooked vacuum lines.  I reconnected everything (hoses), I did not start the engine because I was still working on it.  My engine was running fine for weeks even with P2189 - not rough like some mentioned!

    Two days later, In the morning, I used the car to do errands, I drove for about 10 minutes.  At the stop sign, I stepped on the brake, the car won't stop like it used to! It rolled slowly and then stopped.  It's like taking a much much longer distant to stop.  I did not see anything abnormal on the dashboard except for the CE for the P2189 code! no smell of anything.  I continued to drive the car at the normal speed (35 mile/hr) but kept a large distance from the car in front.  About 10 minutes later, the brake felt normal like nothing had happened.  I drove for another 10 minutes to reach my destination.   2 hours later, jumped in the car to drive home, the brakes felt normal.  About 2 minutes the PSM light came on,  brakes are still OK.  5 minutes later I pulled into the bank, turned off the engine for couple minutes then restarted the engine, the PSM light is OFF, the brake is normal... I drove home.

     

    Now, where do I start troubleshoot the brakes and the PSM light? I don't have the Durametric tool.  Or must I have the Durametric to troubleshoot? can I rent one from someone?

     

    Your help is needed. 

     

    Thank you in advance for your assistance.

  7. Thanks for the tip Loren. I checked all ground connections, adding additional ground wire on each side of the tail light (just to make sure) and sanded the contact points at the license plate lights, well... that didn't solve the problem! Is there such thing as "light control module" that could be bad?

    My next try will be tab on a tail light's circuit to feed the license plate light externally, just for testing purpose. Will this do any harms? or may be I will get another warning indicate that the tail light is failing because it draws more current?

  8. Hello All,

     

    The warning "!" indicated that my License Plate lights are out.  I checked - the bulbs are fine (I replaced with new ones just for the heck of it!). The fuse is OK because when I take the bulbs out and put them right back (like creating an open circuit) - start the car, the message is gone, I check the lights - it's OK (working) BUT as soon as I press on the break to put it in Drive, the message came back on and lights stop working!!! and I can repeat this step!

     

    At the same time, when I start the car and drive, the dome light is on until I hit the dome light switch.  When I turn off the car, take key out then eventually the dome light turned off by itself.

     

    I don't have any Porsche diagnostic tools except for a generic code reader.  The "Check Engine" light is not on.  Both batteries replaced by the dealer about 20 months ago.

     

    My car is CayenneS "04 with 102K mikes on it.  Any suggestions are greatly appreciated.

  9. I bought the car used (04 CayenneS - standard audio - no NAV). At the time I took delivery of the car, the dealer informed me that the amp is bad & gave me $500 discount... I bought a used amp on ebay, changed it out myself (it was a task!), solved the problem! sounded great!... about two months ago, I got no sound. I brought the car to the dealer for battery issue and ask them to check the audio system. Sure enough, they said the amp is bad!

    I really don't want to replace the amp again, instead, I want to upgrade to an aftermarket (Kenwood or Pioneer) system but I read a lot about getting error code if I'm not using the factory amp! is it true? What options do I have? I prefer to install new system myself if I have wiring diagram.

    Can anyone advise me?

    Thanks,

    ManN

  10. Let me add to this thread: my Amp is dead, I have replaced the amp once before and now the one I replaced is dead again!

    I read from "completed aftermarket Navi install" by Cayenneturbo - excellent information - however, i believe he reused the factory amp. My case, I just want to use the amp in the Kenwood, therefore, no fiber is going to be used. Will I get a trouble code if I don't use the factory amp?

    Thx,

  11. Hello all,

    Many sites referred transfer case oil is the same as ATF oil. But in the spec sheet Loren posted indicated different part number for the Transfer case & ATF (ex: Transfer case: 000 043 205 09 or (LT71141) --- on the ATF bottle I bought: 000 043 205 30).

    When I opened the ATF bottle, the color is brownish (normal oil color), not RED not BLUE. I already drained the fluid from the transfer case! Please advise!

    Thank you,

    ManN

  12. Hi All,

    I have '04 CayenneS. I'm planning to install an aftermarket Audio/Nav system to replace my basic stock Bose audio system (non-Nav). I searched in this site & found some audio system schematic; I hope when I take everything apart...the color code will match!

    Anyway, I want to re-use the stock power cable, speakers & speaker wires, antenna wire & stock subwoofer & its amp; can I leave everything else in place? (i.e. fiber cable & other com cable). Will I get any error code?

    Do I need to fish the speaker wires from the head unit to the rear penel so that I can splice to the old speaker wires? Will I expect to find all the old speaker wires in the rear side panel?

    There are many questions in my mind but I can't seem to focus to write them down. maybe this will generate more Q/A for me.

    My 2 choices of the head units are: Kenwood DNX 9960 or Pioneer AVIC140bt or ... maybe you can recommend something better...

    I hope I provide enough info to generate more Q&A.

    Thank you in advance for all inputs.

    ManN
