Abs / track

[v70tom]

Hi,
Just exchanged on the v70. The wishbone and link bar.
The old one was defently ready for the bin.
Now no noise anymore but as soon I drove off the abs track warning light came on.
We did not pull the cable do anything on the abs sensors.
The disc been dirty from holding it with grease fingers but used a rack to wipe it off.
Anything I missed or should do to get the lights back off.
Help please!

May worth to say,
Last night I brought the car in the drive and started it up, turned complete to the left, the abs was loud to hear on the front left side.
Or tracking, but this rrrrrrrr noise. As soon I turned to the straight and stopt it was gone but the light came on again.
Would this mean the left side needs doing with a new wishbone as well?

Ideally the wishbones should be changed in pairs, like any suspension part. The ABS light is probably on because the reluctor ring is either dirty or broken.
