2018 RS5 only one exhaust valve opens in dynamic
Hi guys. new to the forum!
Have a question about my 2018 RS5.
2 months ago driving down the motorway in dynamic mode my friend who was in car behind me at time told me that exhaust gas was only coming out of the right hand exhaust
After stopping at the destination to check, I noticed that the left exhaust valve was closed and that indeed smoke was only coming out of the right hand one. This is with the vehicle in dynamic with the hand brake on.
When the engine is off, both exhaust valves are OPEN
When engine is switched on in comfort mode, both exhaust valves are CLOSED
When engine is switched on in dynamic mode on P or N, both exhaust valves OPEN
BUT as soon as I change into D or S in dynamic mode, left hand exhaust valve closes and only the one on right hand side is open, and exhaust gas only comes out of the right hand side valve
Is it normal for this to happen?
Thanks in advance

Yes. I followed my wife and noticed mine had some Tourette’s like random opening and closing all the time.
Step on the gas more and they will both open up.
Or disconnect the wire wire harnesses and they’re open all the time!!!
