    Hi and welcome.


    This is surely an electrical fault. If the car were mine, I would start with here. Do you have wiring diagrams for this car?

    If you look at my blocked calls list and listen to some of the resulting voicemails, you would never think that it's illegal to make robocalls to cell phones. :mad:

    Those faults don't show "short", they show "open".

    It is, and I expect the regulatory authorities would come down on VW/Audi like a ton of bricks if it were possible to "code out" that system.

    I'm not sure what "apparently" means in this case. Have you've verified this in a proper parts catalog?

    OK, so the airbag module in that scan is: 6Q0-909-605-AF/001, i.e. the Index is 001.


    At a minimum, it will need to be coded.

    With some cars of this vintage, you may also have to update the...

    Yes, OCJ would be the index or color code. These terms are used somewhat interchangeably. If you were ordering, for example, an interior trim price, then that suffix to the part...

    I guess the first thing I would do is to pull the connector(s) from ECU and check the condition of the pins. There should be no water in there, and no corrosion.
