My 2015 passat came with g12 now 61000 miles, no trouble. build date was may 2015. Does anyone know if they installed different heater cores in later production cars and when they started using g13 in the passat. My golf, built same month, is a g13 car. Any test data as to thermal chemical breakdown comparing g12++ vs g13?
