W204 M274 1.6 petrol/ petrol smell help !
I started having some troubles with her. It started smelling like petrol in the cabin and outside. I am worried.
It doesn't do that all the time. Most of the time happens when the weather changes.
I smelt the tank cap and doesn't come from there.
The exhaust smell seems fine as well.
It might be something from the engine area. Maybe a hose leak? Any advice please? Is it expensive to fix?
Thank you!
