speedo isn't working

Are you sure its the sensor? They rarely give issues, it's more likely the wiring from the plug. Brianmooore will give a better explanation, but the copper in the wire hardens over time and starts to breakdown.
The usual fix is to the replace a length of the wire (20-30cm or so) from the plug. An E30 headlight plug and wiring can be used and is likely in better condition as it hasn't spent a 25+ years under the car lol
Another issue can be a dry joint on the back of the cluster, if the odometer still works when the Speedo doesn't, it's likely this is the problem.

Here's the link for the sensor http://www.realoem.com/bmw/enUS/showpar ... Id=33_0121 but as jmc says it's far more likely to be a break in the wiring from the sensor.

Have you tested the wires at the sensor?

Have you taken any notice of the advice you've been given here?
