The light with spanner came at first,then the tracking light came on.when the car is restarted the tracking light is off but spanner light remains on.After a few days the emission light and spanner came on.Now the emission light is the only one left on after a few miles.There is no drop in power or engine stalling.Can anyone advise please before being rip off by dealer.Thanks in advance.Amo de
