Other than buying a new sensor, I'm out of ideas.

The BMW sensor is, I believe, a Hall Effect device. Basically there is very little that can go wrong with it. (It's just a disk with some cutouts and a coil of wire) If you are sure of your wiring I would more suspect the other end - the Speedo. It may be new but it is electronic and far more likely to fail than the sensor. It may be worth contacting the speedo manufacturer and see if they have any idea's.
The best test would be to try the sensor with something you know that works - the BMW dash if you still have it would be good.
With all electrics and electronics fault-finding is often a process of elimination (Sorry if I am taching you to suck eggs..)
