Enabling BC_DIGITAL_V in itself is not enough, if you want to see the real measured speed - in this case, you have to disable BC_DIGITAL_V_KORREKTUR, too. Since speedometers aren't allowed to show a lower speed than the actual speed, and an exact speed measurement is not always possible, all manufacturers correct the measured speed slightly upwards in order to comply with ECE-R 39 regulations:

Look for the formulae under Annex 3, Section 2. The U.S. regulations must have a similar counterpart, too.
