Hi everyone, I purchased a 2011 model with a 206+ 1.4 gasoline engine on Monday. The owner said the engine malfunction light was on because the spark plugs weren't the correct series for the vehicle. The trip computer also gives an Antipollution error. I also believe it's really the spark plugs. What is the original spark plug series for these vehicles? Thank you for your support. Also, is there anything that can be done about the darkening on the left side of the trip computer? Regards.
