    Adjusting High Beam assist on/off speed (B9 A4)?

    How can I adjust the speed cutoffs for high beam assist on my B9 A4? I assume it is a basic setting or adaptation, but which module?

    Thanks,

    I don't know if that can be altered but I'd look in A5 followed by 09.

    It should be an adaptation channel in unit 09 but the needed session and/or security access is unknown.
    20113 does not seem to work for changing this channel.

    On MQB platforms you have to be in Engineer Session for changing this (which is not possible with VCDS except for a few units...)

    The S12345 Login does change to the Engineer Session. Or is it missing from the label you require?

    S12345 does work on several MQB BCMs.
    I don't think this will work for MLBevo.

    In a german forum we had recently the case that changing this on MLBevo even in another session did not work.
