To reset the check engine light on a 2000 Mercedes E430, you can use an OBD-II scanner to clear the trouble codes stored in the vehicle’s computer. Simply plug the scanner into the OBD-II port, turn on the ignition, and follow the scanner's instructions to erase the codes. Alternatively, you can disconnect the car battery for about 15 minutes, which may also reset the light, but this could also reset other electronic systems.
