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?
2000 Boxster Tiptronic with 113k mi. I recently removed the transmission to deal with another issue, but while doing so some of the brittle SAI hoses cracked and/or became disassembled. I have replaced the cracked lines (i.e. not all of the lines) and reconnected according to the following picture, with the exception that I have a Tiptronic and there is a hose that runs to a changeover valve on the transmission:
I get the typical SAI codes, P0410 (80) and P1411 (208), about every 150mi driven. Otherwise the car drives great...SAI pump is running and holding air as usual.
Presumably, I have something connected incorrectly, possibly with respect to connection to the transmission changeover valve. The one thing I notice different than before removing the transmission is that the car seems to be running cooler than before. I suspect this could be caused by the changeover valve for the transmission as I think it controls the flow of coolant to the ATF cooler (not sure about this and hoping for clarification). The other thing that I don't really suspect, is that the new hoses used do not have the small bulbed end to help with that snap-fit into the intake sleeves.
I have not found a good image showing the SAI hose routing for a 986 Tiptronic, so if anyone knows of one I would be very grateful. I have the Bentley manual which also does not show a Tiptronic-specific diagram for SAI routing.
Any other ideas or does this sound like simply incorrect hose connections?
Many thanks for your input!

I need to replace the ATF wiring harness in my 2002 986 w/ tiptronic due to a defective temperature sensor that forms part of it. I have been unable to find any information as to what it entails and / or how it can be replaced. Appreciate any insight.
Hey everyone, i own a 2010 porsche Boxter 2.9L with the PDK transmission.. yesterday after leaving the car for a 4 days i started it and went for a drive.. when i turned it on again, i got a warning message “emergency transmission run” and the car became very jerky through gearshifts and wouldnt accelerate properly.. after turning it on and off the message went away and it drove just fine but then it kept re-appearing mid drives and becomes very jerky and clunky...ive noticed since i had the car that the gearbox was sometimes clunky or would make a noise when changing gear but the dealership said that was fine and normal since its a PDK, the car is at 59,000km so its time for a transmission fluid change... could this be a low voltage problem, or transmission fluid? The reverse gear works just fine.. has this happened to any other owners?
