Cause: Your Vehicle Order (VO) is corrupted or E-sys cannot verify the checksum. Fix: Use E-sys 3.25.3 to "Edit" the FA (Vehicle Order). Remove any non-standard characters and recalculate the checksum by hitting the little calculator icon. Important: Do not use PSdZData v51

Removed: Support for pre-2015 3G TCU modules (TCB/TBM).

Remove the annoying "Accept" screen that appears every time you start the car.
