    older dongle--newer cars

    Hi all,
    Should my KEY-USB with latest version on my computer work on a 2014 Passat and 2017 Jetta?

    I have a airbag light on the Passat and it is saying it does not see the controller. No readings possible at all. The generic OBD scan works fine with my non-VW older cars and it worked fine on my older VW's. This may be the first time I used it on our newer VW's. Not sure.
    Must I move to a newer dongle or am I having an issue?
    Thanks.

    No, a KEY-USB can only communicate via the older K-Lines, while both the cars you mention require a direct CAN bus connection.

    Yes. Discounted, trade-in upgrades are available here. You are in Category 3.

    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.
