On the board of the Megane Classic 2005 I was lit by a witness that SERVA says, what should I do? It is an alarm for what? Thank you for your support. Camilo
That witness warns you to change the distribution band as well as a basic refinement, it is nothing to record that light, do not worry, it is only a maintenance warning, of course depending on the mileage of the vehicle you want if it is time to change it.
