Ok remove the speed sensor and put a drill on the piece that sticks out of it then rotate the piece with the drill and turn the key on does your speed work then ??
Customer: replied 6 years ago.
the sensor is a solid piece of black plastic, there are no moveable parts?
Expert:  vwtech0405 replied 6 years ago.
Look on the inside of the sensor you should be able to spin the black piece in the middle we put a drill on it

oh ok I thought it was a different sensor, I have to step away for an hour, I will try and see if that works when I return

Ok, Sorry for the delay, yes when I put the drill on the tip of the sensor the speedometer worked fine
Expert:  vwtech0405 replied 6 years ago.
Ok then the issue you have is that the speedo in the transmission has split in half you will need to open up the transmission to replace this piece very common issue . I hope this helps.
