I've not come across this problem where the parts are good working items and have been coded correctly in over 50+ retrofits I've now done.
I would certainly do what Timmyboybunter has suggested just to see what happens, no arm in doing so.
As the coding is correct, then I doubt it would make any difference in removing the coding and parts and putting it back to how it was before as you'd still need to undertake the Tool32 stage to reset the steering angle sensor.
