Check Engine light and maintenance key on Dacia Duster

To reset the 'Service due' message and the orange key light, you can try the following steps: Turn the ignition on without starting the engine, press the accelerator pedal fully and hold it, then press the brake pedal three times. Release the pedals and turn off the ignition. Start the car to see if the messages are cleared. If the check engine light remains on, it may indicate an underlying issue that needs attention. Please let me know if this helps or if you have any further questions.
