Used MSG, No PIN (WFSIII)

How do you activate that in the vehicle? Is there a kind of master PIN to get the device to start working?

a) Retrieve PIN from the merchant (via fax inquiry).
b) Read out the EDC15/16 module and, in this way, determine the PIN.
c) Use a compatible diagnostic tool to read the engine control unit and, in this way, determine the PIN.

Those are some of the options that would be suitable for the average user...

No, then we could just skip the whole WFS thing.
