Re, fabia 3 , 1.2tsi 110 petrol

Hi,  my dashboard emissions light stays on while driving,  but the performance doesn’t seem to be affected apart from about a 5mpg drop in consumption I think .

the car has been left standing quite a while during lockdown.

Any help / diagnosis / or  advice appreciated

thanks

 

You need a diagnostic scan to find out why the emissions light is on, then post results here.

 

Otherwise you're fishing in the dark.
