: Learning new car keys (especially for Smart 451/454 models) and resetting VIN data in modules like the ABR/ESP.
: Deactivating belt warnings, 120 km/h speed alerts for specific regions, and mirror-folding functions.
Work on older models where online support may be limited or discontinued. Compatibility Note
: Re-arranging service memory in ASSYST PLUS and manual calibration of level sensors for Airmatic suspension. How It Works in a Diagnostic Workflow
: Modifying VMAX (maximum speed limits) and lifting NOx torque restrictions on trucks using FDOK XT/XN calculation codes.
: Manual DPF (Diesel Particulate Filter) regeneration, EGR adjustment, and clearing emissions-related fault codes (SCR/AdBlue).
The calculator unlocks a wide range of "Special Functions" across various vehicle systems. Common applications include:
: When attempting an advanced task (e.g., "Teach-in of new key"), Xentry will prompt for a password or display a "seed" code.
To use these special functions, a technician typically follows this process:
: The vehicle is connected to a laptop running Xentry via a multiplexer like the MB Star C4 or C6 .
