Only thing I can see is that the sensor has gone into the hub a few degrees offset and the bolt doesnt line up, I remember when I put the sensor in some months ago and trying to twist it to line up but it didnt move, I left it as its not going anywhere.... Could this be the problem? Its a tiny amount. Abs ring looks fine, shaft was new in the last couple years.
Only abs module connected for speedo purposes.
