Hi again. Thanks for the reply.
I get no codes.
I am not topping off the tank, there's max 50 liters of gasoline in the tank. (It can hold 70)
The car is in Turkey which is not in EU. I wonder if the recall is valid there, too. Maybe I should call Volvo customer service in Sweden (where I live parts of the year) and ask.
How do you check the fuel system for leaks? I have not seen any visible fuel leakage, if it was visibly leaking it would smell a lot more, I had that in another car before. When the engine is hot there is always air drift below the car because of heat difference even if the engine is not running. It makes it hard to localize the origin of the smell.
Thanks.
