All the light shows is that there has been a malfunction, or misreading, somewhere.
Without a fault code or a specific problem there is little point speculating
sorry but how I can do that? with an obd?
It's done via the OBD port - this is to the right of and below the steering wheel ( on a right hand drive ). Many code readers available and any garage should be able to do it for you.
It will produce a number such as "P****" that will then telll you where the fault has been logged. If you get it done with PSA software, either Planet or Lexia, this will give a much better reading
