hello guys im the new owner of a 200 A4 1.8. the car drivers fine, but there is a gasoline smell that I think its coming from the trunk or some place in the rear of the car. I had the timing belt done and a day later i noticed the check engine light come on. Took it back to the garage and the tech said it was nothing to do with the work he did. I had noticed the smell berofe i took it to him. any suggestions on truble shooting ?

 

Why do you think it is coming from the trunk and not the engine bay?
