I got my car used and it already had the exhaust system on it. I could only hear the noise my left actuator was making if the car was in accessory mode (key on/engine off). It sounded like a really noisy fuel pump running. Had a neighbor, who is a dealer tech, bring his laptop home and do a relearn on it and that fixed the problem. Not sure if that is the same issue that you are having or not. If the dealer hasn't tried a simple relearn, you might want to try a different dealer.
