i had a local dealership look at my cel 7 times within a month and a half. cel is p0457, emission leak, loose gas cap. The service manager told me they cannot find the leak and I need to go somewhere else to get it fixed. The fuel pump gasket and the fuel cap has been replaced twice, blue t piece vacuum has been checked, turbo inlet repaced with oem.
At this point the mechanic smoke tested it multiple times and cannot find the leak. I will take it to a dealership on tuesday, but i want to try to find the problem myself tomorrow. Any advice would be greatly appretiated.
