Hi I’m getting the catalytic converter light come up. Two days now the same sequence I do a longish journey stop for a short break .. start up and a minute or so later the light comes on . I reset it with Carista and all is fine .
Can anyone shed any light on this ?
 
EGR restricted flow/blocked. Could be a number of other related problems too.
