My emissions warning light came on the other day after I'd just done a long journey, stopped for a short time then started off again.
It was on again the next morning so I called my local stealer to book it in and he told me not too worry too much if they car was driving as normal and it is likely if it was a minor thing from one journey the light would go off in a few days.
A few days later and sure enough it has gone away and everything seems ok, is this normal?
