Car feels like it's filling up with fumes

처리 내용

Exhausts inside the car is not healthy at all. As someone said, perhaps another mechanic should be considered. As to the problem, it sounds like the exhaust pipe is leaking before the catalytic converter. The engine light would likely light up because of this, since the Lambda (Oxygen) sensor in the converter would be receiving less exhausts (and more oxygen) than expected. As Nelson says in the comments, a leak after the catalytic converter would not be detected. I don't know if that's the case on an S80, but many cars have a "flexible hose" kind of construct between the exhaust manifold and the exhaust pipe which can leak without visible holes. To ascertain where the leak is, look under the hood, around the front wheels and under the car when running. Try plugging the rear end of the exhaust and see if a pressure is built up, if the exhaust system is okay it should.
