I have a 2007 328xi and am having a strange abs issue: whenever I sharply turn left the front right ABS sensor outputs zero. I’ve attached a picture of a graph of the output from my OBD scanner. As soon as I turn back to a straighter direction the output comes right back up to normal and doesn’t have any other issues except for in a sharp left turn. Any ideas what on earth this is? Thanks.

Loose screw or wire on the sensor is my first guess.

Bad wheel bearing is my second guess.

Have you checked the routing of the cable and that it is firmly plugged in? My first guess is that the cable is getting stretched in a turn and is dislodging from the connector.
