    For VW still need a custom harness, but otherwise the comma2 has everything else you need.
    As it's new hardware there is some integration work still to do with VW, that will happen in the near future.

    Join the Discord and check the pinned messages at the top of the volkswagen channel.
    Keep in mind we only got it running last week in PQ/NMS so there is a way to go yet. But if you want to get involved at the beginning of what will be a very exciting journey feel free

    Since you stated that the NMS Passat has "ACC Low", and the Comma.ai wiki (VW page) describes the stock function of both ACC High and Low, what happens for ACC Low after the driver takes over braking? Does the ACC disable but can then be resumed from a stop with the steering wheel RES button?

    Also, curiously, the VW GTI in USA does not have EPB, yet is equipped with factory ACC High. Makes me think this whole ACC High/Low scenario is not settled...

    Open pilot will disengage on brake push the same as factory ACC.
    So after coming to a stop you have to resume if you don't have follow to stop.
    With follow to stop OP is able to resume when the car in front moves off.

    Tja has the same behaviour but OP can do a resume from a longer stop (though not indefinitely)

    Also the PR codes are just not ACC high and ACC low.
    There are multiple variants (I don't know what they all are)
    But things like - ACC low with follow to stop and City Emergency Brake. ACC to 160kmh.
    Or
    ACC high with follow to stop and City Emergency brake. ACC to 210kmh. Cyclist detection.

    Here's what I found for PR codes - Google Translate

    Would OpenPilot bring my car to a full stop without MFD alerting me to apply brakes?

    Not with ACC low without FTS.

    Well...it seems that OpenPilot enhances the current system but won't get me the function that I really want.

    Do you know of someone reputable who can "hack" by FeC/SWaP for ACC 'Follow-to-Stop'?

    Followup:

    7N0 radar has FEC changed to 10003700 (ACC high; FtS; FrontAssist; CityANB).

    ACC works & FtS tries to stop but ABS releases around 10mph. If i don't apply the brakes, ACC will automatically resume, but if I apply the brakes, RES button starts ACC at any speed. It closer but ABS isn't fully cooperating yet. Word is, there's a GTI in Germany with MK60EC1 and 7N0 radar with FtS. More work needs to be done...

    EPB retrofit completed using 56D module from Chinese NMS Passat. Still trying to get FtS working but it seems 01-ECM may be withholding the function.
