I'm very new to Fabia's and got an older example (2005) 2 months ago which is used for mainly shorter local journeys.
The EML came on a couple of weeks ago, then 5-6 days later went off. It stayed off for a duration of about 8-9 days.
The same thing has just happened, although this time I consciously took it for a higher speed run when the light was showing, and after another journey a few hours later, the light went off. On the first occasion a friend put a basic code reader on and it showed an O2 sensor had recorded a fault that had subsequently been overridden.
Car has done 108K miles and still runs very well when the EML is on, and MPG is unaffected.
Any reason to investigate and try to correct? MOT is 9 months away.
Thanks
