I have this passat and I’m struggling to fix evap leaks. I have replaced: Fuel cap Purge value Leak detection pump Drop the fuel tank and reseal the the part where the fuel cap connects to. I also smoked the car to find leaks and I sealed everything I could see. Yes I smoked every evap line and fuel tank. All the patches and things I replaced helped to remove some codes but I still get: p0456 and p0441. Sometimes I get a warning light the fuel cap is not on but it is. New fuel cap too! ---

Had the same codes on my old Corolla and replacing the charcoal canister fixed it. ---

Really? I haven’t changed it because its 300 dollars. What happens if it isn’t? What else could be the problem? I remember smoking the charcoal canister and nothing leaked.
