Version coding of control unit


When replacing a control unit, it needs to be version-coded to function correctly. The version code can be read out from the old control unit as the data list parameter "Version coding". Valid version coding is also found in workshop manual or similar.

Incorrect version coding may reduce the car's safety and function.
