    Look the diag; the car have a crappy idle and very bad acceleration...

    Sigh...mine has a similar issue...except that it is a super smooth idle. But once i press the gas is lunges forward like it's skipping gears but it's a CVT...then it vibrates at around 65 mph...I'm getting tired of this car.

    Definitely check coils first. When I got coils replaced under CPO warranty on my 2005 A4 3.0, this is what my VCDS scan showed.
