Wheel sensor pops up- Disco 1

ABS sensor light on despite new sensor, hub and lotsa dollars!
The diagnostics indicate wheel sensor pops up on left front hub and does not cancel ABS light. New sensor and wheel hub fitted but same problem. A second start sometimes cancels ABS light but failed its warrant of fitness, and we are all stumped....any help appreciated.

I take it your getting air gap code usual things wheel bearing play,swivel hub play,worn stub axle,worn stub axle bearing and worn cv.i take it you changed the sensor bush?.
