    Security Code

    Hi Guys,

    I need to change the coding of a VW Passat ACC radar sensor with part number 3C0907567
    Currently in adaptations channel 2 is locked, to change it I need a security code. please help.

    P.S.: I tried the recommended security code 21056 (VCDS says it is for channel 1-8, it is accepted but it is for sure not for channel 2).
    Regards,
    Dr. Kay

    This doesn't really belong in Product Support. Is this another ACC retrofit you're doing?

    The engineering problems are likely insurmountable. It would be like proposing to land a rocket booster section on a barge floating in the middle of the ocean.

    Hi Uwe,

    Sorry, I realized that late.
    It is not a retrofit. It already exists on my wife's passat, but the coding is locked in the adaptation channel 2, and cannot be enabled without a security code.

    This module should be covered under label file. Unless redirection isn't working correctly.

    Please post auto-scan.

    Redirection works and the module is covered by label but the security code recommended is not for channel 2 (lock/unlock coding). I desperately need that code.
    Sorry for the delayed reply. I am down with a nasty flu :S

    Hi all, just to conclude the thread. I figured it out myself after a painful day.
    21056 is the security access code, however to set the adaptation channel from 1 (locked) to 0 (unlocked = coding is allowed), one cannot enter 0. It gets rejected exactly as if the security code doesnt cover this adaptation channel. Input 201 will set the channel from 1 to 0, and then life is good again

    The label just mentioned 0 and 1, perhaps an update of the label would help fellow users.
