How to reset the service light on the Citroën C4

Model: Citroen C4 MK 2 - Years 2010-2018
Part: Service warning light

The steps that make up the procedure related to the Service Engine Light reset are simple and quick to perform on a Citroën C4. To perform the reset, we must get into the car and turn on the instrument panel while simultaneously pressing the button located under the odometer. We hold the button down until the end of the countdown appears on the display. Once the countdown is finished, we restart the instrument panel to complete the reset procedure. If the light still appears on the instrument panel when starting the car, it will be necessary to go to a workshop to perform the reset using an OBD socket and diagnostic computer.
