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.)
Instrument cluster completely dark and gauges not moving.
How to save $5000 in 3 easy steps.
2002 Boxster S
Here is my story, the problem AND THE SOLUTION.
I have a 2002 Boxster S which was sitting for approximately 6 months unused. As you might expect the battery was dead when I went to use it. It was easy to jump with a portable jumper starter. The car started right up and it was easy to drive. However, when I stopped to get gas, the dashboard instrument cluster went crazy and all the idiot lights came on. Even though I had driven the car for about a half-hour the battery was dead, so being prepared, I use my portable jumper starter. The car started up fine, however all the idiots lights stayed on. The instrument cluster otherwise worked. Drove home, left the doors slightly open so that I would not get locked out, and open the hood so I could get to the battery, then turned off the car. Shortly thereafter drove to get a battery, but now all the idiot lights were on and the instrument cluster was completely dark. Gauges were not moving. Nothing! The battery was replaced while the car was off. After restarting with a new battery, the gauges were not moving, the instrument cluster was dark and now only the check engine/oil pressure idiot light was on. Drove home and turned the car off. However, the check engine/oil pressure idiot light stayed on, even though the car was off. I asked my local mechanic who recommended, "Just take it to Porsche". So I called the Porsche dealer, who could not take the car for a week, but figured it needed a new instrument cluster and after diagnosing fees and the all the other fees and costs would be a few thousand dollars. So, I decided to search the web. I did not find an example exactly like mine, but after my research it seemed that the main computer might have been confused by too many low-voltage signals since the battery was weak. I was sure there had been no overvoltage situations or sparks. I had little to lose, so I thought I'd try the following which worked!
Tools needed: 10 mm socket wrench and portable jumper starter.
Disconnect the negative (black) cable from the battery using a 10 mm socket wrench.
Reconnect the negative (black) cable to the battery using a 10 mm socket wrench.
If needed use the portable jumper starter to start the car.
Smile and save $5000.
The instrument cluster is working perfectly and all the idiot lights are off, even the radio works! Hope this helps someone else!
I have a 2003 Boxster base model (2.7) with auto. Current showing code P0600 and DTE 61. Had a few different Porsche mechanics look at the issue and have not found a solution. Cleaned the electrical connection at the transmission and verified the ground connections at the tiptronic control module. Had the DME, tiptronic module and immobilizer checked and they were found to be working.
Does the Can-bus connection between the DME and the tiptronic module extend to the immobilizer or other modules? All I could find is information up to the 2001 model year.
Looking for a reason why the DME Is not communicating with the tiptronic and how to test the Can-bus circuit. Is there a wiring schematic available for the 2003/2004 boxster?
