Might be the rings on the drive shafts have corroded so you are not getting a good signal at the sensor. Should look like this

Time for an overhaul of my 1.9 '98 BMW Z3 Individual

Also make sure you bought the right sensors @pgunter can advise how easy it is to get the wrong ones

Make sure that the battery is fully charged, by a run of about ten miles, as the Slip control Module is very sensitive to voltage. I find the my ABS and traction control warning lamps will come on even after prolonged use of an automatic charger, but a quick drive always sorts things out.

I've had the same problem, replaced all 4 speed sensors but the engine light would not turn off. replaced both throttle position sensors, updated the ecu software,nothing.
the engine light went off when I replaced both intake boot and oem (800 bucks) MAF sensor. problem solved
