The speedometer on our 911 was not working either. Speedos measure spinning magnets that are glued to a disk in the transaxle. Sometimes they come off. I replaced the disk...didn't fix. Sent Speedo to a shop in CA and they said unit was fine. Even took car to master mech at a Porsche shop, he couldn't solve issue either. Turns out our problem was the ignition switch. The speedo has one wire lead coming from the back of the switch. I determined that needed replacing when I ran a wire from the battery directly to the speedo. Replacing the ignition switch SOLVED out problem.

There is a gear in the speedo that breaks. This is plastic gear on a metal shaft. The last fix I did was to remove speedo and open it up. I super glued the cracked gear to the shaft because I was unable to find a new one. It worked again with no future problems. I hope this helps.

This is all related to the vehicle speed sensor. This sensor sends information to the speedometer, abs, and wing computer. You need to get it replaced and it should fix all the problems.
