FRUSTRATION! I recently purchased from the parts department of my dealership the "Navigation Update" (958 044 902 51) which has been made available on Porsche's Techquipment site as of this month. Although there is no date associated with this update, it is apparently new as of 2014. It turns out that the purchase is nothing more than an authorization key which allows the dealership to upload maps which it has in its possession and receives periodically. The update claims that there is a "significantly higher degree of detail . . . and additional POCs". I cannot detect any of this after the update was performed. Upon asking the dealer, I was told that the latest version is 997.642.273.56 - Map Data PCM 3.X – 06.2013SW versions: 7PP.919.193.CC. That is, the version is from June 2013. And I wonder - what have I paid for? There is no literature available from Porsche as to what has been actually updated in this version of the maps. There is nothing visible, there is apparently no way to know the actual map version that has been installed, as there is no way to seek this version from the PCM itself. And further, how is the latest version of maps available to the dealer from June 2013? The response from the dealer is ignorance as to all these questions. Does anyone have any insight, advice, similar frustration???? At least, the only actual visible update that I got was the PCM software which went from v. 2.4 to v. 2.46.

6.2013 is the map data for 2014 model year. We at the dealer usually get these updates about 6 months after they come out. You will most likely not see a change unless there are multiple new roads in your area and points of interest should be updated. The map version can be checked with the Porsche system tester at the dealer.

      I have a 2009 957 3.6l v6 Cayenne. The battery was dead a few days ago so I replaced it. It now starts up just as it should but when run a diagnostic it says the alternator voltage is high reading 14.72. I’m assuming I need to replace the alternator to remedy this. I can’t find any information about replacing the alternator. Has anyone attempted this? It looks like it might be straightforward  but my concern is whether or not the intake manifold has to be removed in order to get clear access. If anyone has any insight on this I would greatly appreciate it.

      Does anyone have a wiring diagram for the seat on a 2008/957 Cayenne which they can let me have?

      I’m trying to chase a fault where the passenger seat will motor up and down and the backrest will adjust forward and aft, but there is no response from the controls to move the seat unit forwards and backwards, or the four-way lumber support control.
       
      Thanks in anticipation...

      The navigation dvd drive in my 2006 997.1 C4S has failed. It will not eject the dvd. I want to remove the drive unit in order to attempt a repair or, if necessary, replace it. My problem is that I have been unable to remove the plastic piece that covers the dvd drive and audio amp.  Porsche said "it just drops down." I have pushed, pulled, and cursed at the cover but it will not budge. I hesitate to use a tool as a lever for fear of breaking the cover.
      Do I need to eat more Wheaties so I can  pull harder on the cover, or am I just missing a simple solution?

      My front wheel was making a rattling noise for about the last week, and this morning as I drove out of my driveway and turned the wheel, I could hear a loud popping noise coming from my wheel whenever I turned. My best guess is that I drove over a pothole and the control arm / bushing moved out of place. Would this be covered under the OE warranty? Or should I take it to a mechanic?
