I have a Subaru Legacy 2003. It has just started to get really cold in the mornings were I live, about -2 And I have found whenever my car is cold and I turn the heater on, a fuel smell comes into the car.Once the car is warm it wont do it anymore.I have been googling the issue, and have seen that a few people say the fuel line may be to short and is retracting in the cold weather and then expanding again when it is hot (this would explain why it doesn't smell when the car is warm)It has been doing this for about two weeks now and I haven't gotten round to replacing the fuel line. This Morning as I was driving to work (it was very cold and frosty) the check engine light came on, it wasn't flashing. When I parked the car and checked it, it smelt very strongly of fuel.Would this fuel line problem be the cause of the CEL ?
Go have the codes read with a scan tool and you will know the answer to that. Without the code no one can tell you for sure what it means.
