    Has the '00-'01 airbag controller bug been squashed?

    Hello, longtime lurker, first time poster. I have a genuine VCDS cable, purchased in November of 2017, and am using version 18.9.1.0 of VCDS. My car is a 2001 Beetle 2.0 GLS, acquired in October of 2017. It has about 126,000 miles on it.

    I see a lot of warnings around about how the airbag controller module in certain '00-'01 Golf, Jetta, and New Beetle vehicles has a bug that gets tickled by VCDS if you try to scan it or make any changes to it. However that page also states that that bug has been swatted and/or worked around in more recent versions of VCDS. It does look, from the attached autoscan, like my airbag controller has the "bad" part number, 6Q0 909 605 A. I haven't inspected the controller physically. Doing so would involve kneeling outside the car in the snow to get the panel off--not a great plan in New England in February!

    Do I still need to worry about this bug, at this point?

    Here is an autoscan.

    The bug in those old airbag modules has never been fixed. I doubt the software in them is can be updated in the field.

    The behavior in VCDS (back then called "VAG-COM") that was triggering this bug was addressed back in 2004. I don't think you need to worry about it.

    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.

    Thank you. I found a bunch of posts on VW forums from ... long after 2004, so I was wondering if this was still a thing I needed to worry about.

    It looks like the infamous unclearable "65535" error can be caused by a lot of different things, including low voltage. I wonder if some people who had this happen for other reasons unfairly blamed VCDS for it.

    Indeed, it can be caused by a number of other things, but early in 2004, we positively identified a a way in which a scan tool could make it happen, and then put code in VCDS to prevent that.
