Data Port/ OBD II Port, What's the Difference
I realized today that my car has both a round engine bay data port, which accomodates my Peake code reader and a rectangular OBD port under the steering wheel. I was always under the impression that the engine bay port was used to read the OBD computer. My X3 appears to have an identical rectangular port under the dash that accomodates the newer code scanners. Does anyone know if there is a difference in the function of these two ports?
