My door locks only work part of the time. At other times, they will click on and off randomly, like when I'm driving, going over bumpy sections of road, or sitting at a red light. I bought the car about a month ago and the guy said the passenger door lock mechanism was faulty, but they both have the same problem. I had to disconnect my alarm horn because it would go off at the same random times the locks acted up. Any suggestions on how to troubleshoot and/or repair this?

sounds like it might be an issue on the alarm/central locking module under your driver seat.

I agree perhaps the module got wet.

That can cause all kinds of strange behavior and eventually corrosion and failure.

Best to have the alarm code(s) read with a Durametric, Porsche PST2, or Porsche PIWIS tester.

      Hi,
       
      My 99 996 has started beeping twice when I press the key fob.
       
      It locks and then immediately unlocks.
       
      Also when opening the drivers side door, the window goes down when handle is pulled but goes straight back up when the handle is released. So the window obstructs the door closing.
       
      I have the following Durametric Alarm errors:
        11
      Voltage failure during alarm
      output
      Status: not present
      Frequency counter: 1 10
      Voltage failure at terminal 30
      with alarm system active
      Status: not present
      Frequency counter: 1 46
      Control locking synchronization

      Status: not present
      Frequency counter: 2 49
      K lead

      Status: not present
      Frequency counter: 1 21
      W lead (DME immobilizer)

      Status: not present
      Frequency counter: 1  
      What's the best way to proceed with fixing this?
       
      Thanks
      Ravi

      Hello Guys, 
       
      I got my 2014 Cayenne Platinum edition and it seems that the remote unlock and locking mechanism using my key fob does not work unless i am close to the vehicle, range is i would say 5 feet. 
      I tried to change the batteries on the key fob but issue still there, is there anything else i am missing or is it a design issue by Porsche that they corrected on a later versions ? 
       
      Thank you,

      I have a 2002 Porsche 996 Cabrio and earlier this year the immobolizer under the seat got wet.   I purchased a used immobilizer, key for and ECU behind the rear seat.  All of the parts came from the some year model etc.  I put the parts in myself and everything worked great.   Now i need a new key fob or atleast I think i do.  The remote work sometimes and most of the time is doesn't.   When its not working I cant lock or unlock the car with the remote and the front trunk will not open with the fob or the switch inside the car.  When the fob works everthing works as it should in the car.  Do you think this is a key fob issue or something else?   Can i even get a key head programmed since these part are from a donor car?  I do have the vin of the donor car.
       
      Please help!

      Hi there, my Cayenne is telling me my driver's side door is open when it is not. This is causing the dome light to stay on. Not sure what the issue is and if can be fixed easily. Any info given is greatly appreciated, thanks!
