I found several threads this was asked in, but no answers. I'm taking my newly acquired 2015 R to the dealership to get it checked out tomorrow. I know, probably unnecessary, but I'll fee better even if my wallet is quite a bit lighter after doing it. Mine is the only car I've heard in person and I think it sounds great, but I don't know if it has been updated or not and DONT WANT IT if it hasn't yet. I found a youtube video that insinuates you can check the software version by holding the valet button down, but I cant find anywhere what it should be for the louder exhaust. Anybody know the answer to this or the real technique for checking?
