Can I check a couple of things...
How many actuators do we have? I gather from the G01 forum that the M40i only had one and it impacts the left exhaust only. I'm assuming we have two, one each side?
The G01 appears to close the left exhaust on start up for faster warm up, then opens after 30 secs, so they get a louder start up, even in Sport+. I think the X3MC is open both sides on start up and closes at least partially as you move off as it gets quieter after startup?
Process on G01 seems to be to drive for 5 or 10 mins to open valves, yet our car it seems to be just cold start it. So the exhaust is operating quite differently?
One guy on G01 forum suggested his valve vibrated closed over a number of weeks after deactivating valve. Is this possible? I thought they were motorized and would be locked in place by the powered off motor.
