Audi A6 3.0T Throttle Issue
 

Hi Members,
I have a 2014 Audi A6 3.0T Premium. when I am driving in Sports mode and press on accelerator the pick is not smooth, i get some jerks and also when I brake i get the same thing. I am not sure whats causing the issue. This happens only when I drive in Sports mode
Has anyone experienced it before?
Please respond friends.
