Hi, my 09 MC Shift has developed an issue with the exhaust sound recently. It appears as though the valves remain open even when not in sport mode. Don't get me wrong, I love the noise but not great when I'm looking to discretely park up on the drive without waking the neighbours.
There is no audible difference in exhaust note when I engage sport mode - hanving researched the forum it seems that some people have experienced the opposite where it is stuck in quiet mode. I've also been underneath to apply some WD40 on the valve/vacuum mechanism which I was able to move around fairly freely anyway so I'm sure this isn't the issue.
Anyone experienced something similar or know a way to fix this so the valves go back to being closed as the default position? No error messages on dash or any other issues with the car that I am aware of!!
Cheers!
Matt
