To clear the ESP BAS codes on a 2001 ML320 Mercedes-Benz, you can use an OBD-II scanner that is compatible with Mercedes vehicles. Connect the scanner to the OBD-II port, turn on the ignition without starting the engine, and follow the scanner's prompts to read and clear the codes. Additionally, you can try disconnecting the car's battery for a few minutes to reset the system, but this may also reset other electronic systems in the vehicle. Always ensure to address the underlying issue that caused the codes to appear.
