If your speedo is dead, and the ABS module was already rebuilt, I'd look into one of the rear speed sensors on the hub.
Quoted from BF:
If the speedometer and odometer do not work, the driver's side rear sensor is probably bad. If the speedometer works but the cruise control does not, then the passenger side rear sensor is probably bad.


You can also test the sensors themselves with the diode setting of a multimeter to confirm, but since we ruled out the ABS module (already rebuilt), I'd say one of the rear sensors. Be sure to buy genuine OE sensors from BMW, not aftermarket Chinese ones.


Hope that helps!
