2018 RS4 avant B9 - exhaust valves

[shields717]

Interested to hear if it’s normal for a 2018 RS4 B9 to only open driver side valve in dynamic or individual (atleast when the car is in park or neutral in driveway).

Trying to determine if i have a bad actuator on the left.

Seeing mixed things on forum feedback looking into the issue.

Any help from B9 RS4 owner would be great!

Thanks
Peter
