    ACC Refused to engage - red pointer

    Our Tiguan would not engage ACC
    pressing the SET button just showed a red pointer on the speedo, where normally it goes green.

    Anyone know what causes this?

    Could it be that it is the speed limit function, not ACC? I think the ACC button cycles between ACC on, Speed Limit on, or all off.

      Is there an exclamation mark beside the pointer?

        No exclamation mark. Just the red pointer, instead of green, or grey.

        could well be. I might have toggled that by mistake, as it was working fine today. I’ll keep that in mind and try it deliberately tomorrow to see. Cheers.

            What I don't get is why isn't the speed limit function on at the same time? I.e. I don't ever want the car to go over a speed I set the ACC at.

              When the ACC is engaged, it does apply the brakes to keep the car at the speed selected.
              I always thought the speed limit option was just to remind a driver who is happy driver in manual/human mode that they have reached the limit.

                Does it remind or actually cap your speed?

                  Cap. Will actively brake going down a hill, to keep me within 1-2kmh of set speed. Golf and Tiguan act the same.

                    But my ACC does that. As the first letter suggests, it actively slows the car downhill and to slow down behind slowing cars.

                      So I would prefer ACC that I can override when I need to overtake, rather than the speed limiter leaving me hanging mid manoeuvre. Lol.

                        I'd assumed the speed limiter was 'only' a chime to remind people to check their speed. And you could boot passed the limit set if you wanted or needed to.

                        Has anyone actually tried it?

                          If you push the throttle hard enough you'll feel a "bump" and it'll accelerate over the speed limiter you've set. At least it does on my Passat!

                            Yes, you need to press the kickdown switch to override the limiter.

                              What’s a kickdown switch?
