Hi , my name is linh . I just buy a new bmw
540i 2018 . First , I really like it . But i found
something wrong with this car . Why the
exhaust at right side alway close ? .
My guess is there is an exhaust valve that opens under full throttle. I suggest you read up on your car.
Is that normal or not?
Many times BMW puts an exhaust valves in there cars they were should both open when your car gets past around 6000 rpm. If only 1 side is saying closed under 6k and the other one stays wide open it might be an electrical issue with the actuator.
