I am having issues for a while now with my 2016 FL S3. Under light acceleration, especiallay on a hill, the car is hunting, nealy like I am lifting on and off the throttle. Even under full throttle I would get a couple of jumps on the way up through the rev range. If I just accelerate at about 2500 rpm then that is when it seems to be worse. I had the plugs changed which seemed to help but it is back again. I have scanned with VCDS and no there are no faults on any of the modules. The car is booked in the week after next and I still have warranty but I was just trying to get some ideas because they said if they can't replicate the fault then they will not investate further and due to the COVID-19 restrictions I cannot go out with the mechanic.
