How can you stop the change oil light flashing on your citroen relay van?

To stop the change oil light from flashing on your Citroën Relay van, first, ensure you have changed the engine oil and replaced the oil filter if necessary. Then, reset the oil change indicator by turning on the ignition without starting the engine, fully pressing the accelerator pedal three times, and then turning off the ignition. Finally, start the engine to confirm that the light is no longer flashing. If the light persists, consult the owner's manual or a professional mechanic for further assistance.
