hello everyone,I have a problem with my A3 1.8Tfsi saloon 8v…when I open the fuel filler cap there’s some air like popping bottle,then a noise starts and fuel starts blowing inside the pipe…I changed the N80 and even the whole fuel tank and keeps doing the same…when I’m going to gas station and trying to fill the gas comes at the edge off fuel filler and slide inside very slow and after a ride when I stop it does a gas mark behind the right rear wheel…any ideas what other to check?
