SKGT07 update – Dashboards and AMG activation – W204, W207, W212, W218, W197, W166, W176, W246, X156, W205, W222, W213, W447:
In this function are added Seed -> Key generation for different modules. 
For each module, the calculation of the algorithm is different. Can be:
27 71 – 4 bytes Seed used for Coding and AMG activation  
27 09, 27 05, 27 0D – 8 bytes seed used for Coding and AMG activation
27 05 - 8 bytes Seed used for Reprogramming
27 61 – 8 bytes for EEPROM access
