The calculator unlocks a wide range of "Special Functions" across various vehicle systems. Common applications include:

Using the Xentry Special Functions Calculator requires a basic understanding of its features and functions. Here are the general steps to follow:

Reset used modules to factory-new status so they can be adapted to a new VIN. 3. Retrofitting and Variant Coding

When the calculator fails, look for an option called "Transfer coding from old control unit" or "Online coding via VIN" — these bypass the manual calculator entirely.
