I had the same issue. It was loose connections on the back of the cluster. Make sure everything is double checked. I had to pull it twice until I found the connection that was doing it.
Hello Guest, welcome to the initial stages of our new platform!
You can find some additional information about where we are in the process of migrating the board and setting up our new software here
Thank you for being a part of our community!

This sounds promising. I have a sedan, but I think I know where the little box the diff wiring goes into, the one that goes up the left side of the trunk right? So I'll just have to get that new wiring set and replace the wiring up to the box?
The connections that press onto the circuitboard behind the speedo? I've pulled it and squeezed each connector so it clamps onto the circuit board firmly. It's on there tight and I taped it in place to reduce any movement from vibrations. After a few days of driving, the speedo seems to fail more during the morning when it's cold and rarely during the day when it's hotter outside.
Yup, you'll have to pry that open. You can also use that test method in the clean flametrap link someone posted above. You don't have to replace that whole harness, usually just cutting back and splicing into a good section of wire is fine. I did make myself a separate harness further down, though. Used a 2-pin connector from the power windows on my parts car to make a shorter harness with new wire. I didn't have time to wait for new wire and clips in the mail, so I used some rubber booted bullet connectors from somewhere else on the parts car, too.
It acted up a 2nd time and when I pulled the clip off, it was full of water. So it's worth buying new wiring with rubber boots that are in good shape. That wiring is subject to the elements more than most.
So after checking everything and driving for a couple months, it boils down to just temperature. When it's morning or at night and it's colder, the speedometer acts up. But if I'm driving during the day when everything is heated up, the speedometer is perfect. What could be the issue? Is the temperature affecting solder connections?
That could possibly be something causing it. I'll have to really inspect the assembly with my dad some time to find any culprits.
