"Surprise Drift Mode" - ABS & ASC error on BMW E39 520i 1996

I got the ABS & ASC lights on the cluster the other day. This is due to an wheel speed sensor on the right front side. As a result both ABS & ASC systems are disabled.
The original plan was to switch the sensors on the front wheels to see if the error moves with the sensor (otherwise it might be different issue - maybe with the cables, the magnetic ring on the wheel bearing or the ASC unit itself).
Upon inspection I decided to change the sensor without further investigation as it's old and cracked (both the sensor and the cable).
I am not a professional mechanic but I will try and answer any questions you might post in the comments.
