I tried the special functions (diagnostic, engine control unit, CAN instrument etc) on VVDI2 Porsche software, nothing display and function not working. Is it normal or should i update it to global version.
Porsche function is not a core function of VVDI2. It is a bonus function. Porsche software now all updated to GL (global version).
VVDI2 Porsche software now only supports prepare dealer key with EEPROM support and learn dealer key via OBDII . EEPROM support: 1L15Y, 2M25J, 5M48H, 1N35H etc
Other functions are under development.
