For the following procedure, use the PIN of the NEW (USED) control module.
There are 2 possibilities how to enter a PIN, choose the one that applies for you.

    • [Use 7-digit PIN/SKC]
    • Enter the 7-digit PIN, Date on which the PIN was generated by the dealer, along with the Workshop Code (WSC) and the Importer number of the dealer that generated the code.
    • [OK]
