In emissions testing mode in my M3, the whoopie cushion moves to whatever seat you press, but the sound is "stuck" at the first seat pressed (unless you go *real* slow). I'm not concerned about emissions testing mode, but that there may be a wiring problem or other issue with my sound system.
Can any other M3 owners confirm... does yours do this?
