I think they could do that, not run the manufacture's code through the standardized OBDII port. Old pre-OBDII BMWs have a round BMW-specific port under the hood. My wife's '97 Z3 has both ports. OBDII goes through the OBDII connector in the passenger footwell. The BMW codes can only be accessed through the 32-pin round connector under the hood.

A manual transmission can be set to "comfort", "sport", and "track" modes simply by the technique and speed at which you shift it; it doesn't need "modes", modes are for manumatics that try to behave like a real 3-pedal manual transmission. If you can money-shift it, it's a manual transmission. "Yeah, but NO ONE puts an automatic trans shift knob on a manual transmission."
