Bad Cam Adjuster Wiring Harness Causes the C1 Fuse to Blow

My 1999 911 Carrera started smoking at a streetlight. Very smelly blue smoke was coming from under the engine cover. I pulled over and popped the cover. Blue smoke was coming from somewhere under the engine (not the exhaust). The engine stopped very suddenly.

 

We don't have a local Porsche dealer, but the Subaru dealer owns a bunch of 911s and he has a couple Porsche mechanics. I had it towed there.

 

The C1 fuse ("Engine Electronics") was blown. They replaced it, but as soon as they turned the key, the "cam adjuster wiring harness" (I do not know what this is) began to smoke, and the fuse blew again.

 

They disconnected the cam adjuster wiring harness (I don't know what this means, and neither did the service advisor), and the fuse stayed intact, and they got the car started. They were able to drive it out to the parking lot with no problems.

 

They said I need a new cam adjuster wiring harness (again, no idea what this is), and this would require an engine out repair, which they could not do. They estimated this work at $5,000 to $6,000.


Additionally, they did not know how drivable the car was with a disconnected cam adjuster wiring harness.

 

So ... how bad is this?  (Service report image attached.)

      996 PSE exhaust going oddly quiet until 3500rpm
      By radial
      To all 996 owners with PSE, especially those with a 4S. 
       
      I think my 996 C4S exhaust behaves oddly. I think it's a fault but you might tell me it's normal behaviour. The problem is that I've always had this 'fault' on my car so I don't know if it's a fault or intentional behaviour. If you have the same car, perhaps you can shed some light on this.
       
      When I start it, it's noisy and sounds great. It quiets down as it runs for the first 5 mins. 
       
      I have the PSE system and when I press the button you can audibly hear the exhaust note change - quieter when on and louder when off. Default is off so loud.
       
      Here's the rub. Up to around 1500rpm it's got a good noise then it fades out to the point where it's so quiet it's like driving my partners Yaris. If I keep accelerating, when I get to around 3500rpm the exhaust suddenly gets loud again. I mean it's immediate - like someones flipping a switched marked loud. It sounds great. 
      It happens in 2nd and 3rd gears most noticeably and the PSE is in the 'off' position. If I have the PSE button on, then it's just quiet all the time and that works fine.
       
      So why the silent spot?

      I did read somewhere that German market cars might have had a system that turns on and off the PSE at certain speeds to prevent people driving round residential streets with a loud exhaust but information is thin and I don't think I was ever on UK cars. 
       
      I have also had a small go at checking vacuum pressure at idle on both sides of the Y piece in the engine bay but both hold good pressure. One side has only a microscopic leak but not enough to cause this kind of issue.

      2005 996 gauges for racing simulator
      By Dlowe
      Hi everyone, I just got a set of gauges for a 2005 996. I'm building a simulator for PC and would like to wire the gauges to work with racing games. I am in need of the wiring diagrams for the cluster. If anyone has a picture or manual that can help me out it would be great! Looking for inputs, power, signal.

      Seat wiring diagram
      By Roly
      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...

      Alarm double beep
      By Ravi Matharu
      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
