Complementing the software is the data package, PSDZData V51.3. In the world of BMW coding, the version number of the data files dictates the range of vehicles one can service. V51.3 is a significant milestone because it captures a specific snapshot of BMW’s engineering evolution. It contains the software definitions for a wide array of modules produced up to its release date.
