Open up the speedo unit and you will find it will have dry solder joints on the connector block pins on the board. Reflow the solder and you will find that will cure it. For preventive medicine for future, get some thin self adhesive rubber strips and when you put the clock housing back together, run the rubber strip around the joins, to make it completely air tight. Stops moisture getting in. Have to use a bit of force once the rubber strip is in place to put the housing back together, but it will help..
It's not a speed limit it's a target
