Now im gonna have to check when I get home. There was a quiet update the other day. I can always tell when they happen because my custom gauges go back to factory default colors and my shift indicator setting goes away
I have heard that before but is very sporadic and subtle. (Almost like a subwoofer waking up with aftermarket audio). I've also had that in BMW's too.
I've even driven it barefoot to to try and see if is negative clutch feedback but is none there
Absolutely man! is some funny YT videos of losers trying to steal cars. they go right past the manual 911's, Mustangs etc and steal the Cadillac, BMW or Benz
They are definitely out there but dealers tend to stock the autos since alot of people cant drive standards.... In Atlanta some dealers stock manuals at 50/50 probably but not nationally
I read the other threads in entirety yesterday, this is like a Robert Stack Unsolved Mystery haha until I pull my as built codes
UPDATE: it does have ESE ON, GT w/ 9 speaker non B&O 301a.
The active exhaust has a physical component too (actual butterfly valves) I also run in quiet mode or normal alot for similar reasons to OP. But my "Star" button goes to Track Exhaust. Mine is a 301a and cant tell if is any synthetic speaker sounds myself
