i own a 1973 super beetle and when i bought it i had the same problem. we fixed it by replacing the speedometer cable on it. the cable runs from the front, driver-side tire and goes in to the back of the gauge it gets a little tough unless you have tiny hands but that fixed it for me.
How I have to do for replace a little bulb on the ODO speedometer cable on 1973 Super Beetle ?
