1 . After the cold catalytic warm up on start up, see if the exhaust is coming from both sides. The sound will literally and figuratively be twice as loud when driving or under throttle, IN ANY DRIVING MODE.

2. The car has to be put in Sport Mode, then while still running, get out of the car and pull the fuse.
I'll try it again, thank you.

By the way: the car is warm right now, in Comfort Mode, I can feel exhaust coming out of both sides, would this suggest the flaps are open?
