Engine Miss
2019 C7 GS A8 with 14k miles has developed an engine miss. It's very pronounced at 40-50 MPH and does not matter whether it's in V4 or V8 configuration. Also, very noticeable when slowing down for a stop light. Car has no mods, strictly stock. It's bad enough to shake the car but no idiot lights. Thinking bad plug wire or coil pack. Any thoughts?
Thanks

Interesting, I have a 2019 C7 manual and i have had a rough running engine since day 1. Very light shudder under around 1200 and seems to go away above that. I have replaced the plug wires and wonder is a bad plug or injector might be the cause. I don't like it but have come to live with it..

I would get code reader and see if there is a code being thrown. My 2017 runs rough when I first crank it up in the morning then it clear up. I don't like that my 2005 never skip a beat. I hope its not the clasped vale thing night mare. I am not getting a code so my finger is crossed.

Seems a little more research has found an answer. According to the dealer it sounds like the shutter issue with the A8 tranmission. I set up an appointment for Friday and will let all know if that fixes the issue.
Thanks!!
