you should be able to test the sensor in the diff with a multimeter, theres two different types of speed sensors, the style generally used by bmw is a switch that opens and closes the circuit, look for conteneuity to pulse on and off quickly as the driveshaft turns. the other style is a ac current generator, the faster the driveshaft turns the higher the ac voltage (i mention this one because i am not sure if a euro model will be the same as our usa cars, so you will know how to check out ether one)
