So my abs lights keep coming on. When I am turning slowly and sharply like pulling into a driveway the thousand dollar chime will occasionally ring giving me the yellow break light, the yellow ABS triangle and the 4X4 skidding car. Then when i restart the car it is gone. Run the codes on MHD and nothing. Weird. My tires were getting old when it started so i replaced them. Still happening. I also recently disconnected the battery to check my blower motor wires to see if i needed to get that done asap.

Any help would be appreciated.

Likely an intermittent fault in the wiring/connector for one of the four wheel speed sensors. See this TIS circuit diagram for the DSC on you vehicle:
https://www.newtis.info/tisv2/a/en/e...ol-dsc/hYo4qNp

TIS schematics are interactive, meaning you can click on any BLUE component ID, such as B3," Wheel-speed sensor, rear right" to see more information on that component such as "Installation Location." If you click on its connector "X143" you can see "Installation Location" or "Connector View."

It is possible that the sensor itself is bad on one of the wheels, but since the fault occurs on sharp turns, that suggests a wiring fault, probably in one of the front wheels. If you can get INPA or some other BMW-specific software/ Scan Tool connected to your DSC module, you can quickly see which wheel sensor/ wiring is the problem (by reading Live Data during the intermittent failure), but a careful visual inspection can also work. There likely is also a saved code in DSC memory since warning lights were lit.
