Recently had the CEL list 3 codes. I fixed the P1518 and have been searching to fix the other two and it seems not many have smelled gas. Anyway went to work with the light on - I didn't reset it as I was still working on the two other codes and went to drive home an no CEL! First Christine fixed the LEDs in the mirror and now this! And yes I didn't smell gas. There is no way this can be caused by a sticking IMRC, so i will keep a watch on this. It was much colder today not half as warm as it has been last month, but do not see how that could stop the smell either.
