Default Carbon build up maybe

Just did sea foam treatment through the throttle body, and my misfires for 1,4,5 are going away according to the scanner ,, its getting better as I start it up and let it get up to temp then I shut it off let it get cold then start it up again

I am new to the forum and shopping for 2018 A5 Sportbacks. I'm impressed with the car, both new and pre-owned. The question I have is does anyone know what "minor" changes Audi plans for the sophomore year of the car? I don't want to break my rule of never buying the first year version of a new model, but I really like it. Also, when does Audi normally release the 2019 models, early first quarter?
