    The rear ones are hidden behind the rear bumper (just between the light clusters and exhaust tails), and used for the side assist. If they fail, they stop the brake assist and ACC functioning, despite the fact they donít technical need the rear radars.

    Yeah itís a pain the ACC doesnít default to regular on failure, however if it did, imagine a lapse of memory, itís not worth considering and I expect why it doesnít.

    If these had failed on yours, Iíd expect a VCDS error on ď3C Lane ChangeĒ

    Turns out they had been switched off, pressed the button and the blind spot system is back on, not sure who turned it off though.
