    Adjusting matrix headlight activation speed

    Hi,

    I'm looking to adjust the activation speed of the matrix headlight high beam on my 2018 S5 (UK model). Much as I did with the high beam assist on my older B8.5 A5, it will suit the roads around here better with a lower activation speed.

    I have done a scan of the adaption map for module 'A5 - Frt Sens. Drv. Assist' and it shows two likely entries for this:

    Code:
    IDE03885-Speed threshold for high beam recommendation off,27 km/h,2
    IDE03886-Activation speed for high beam assistant,57 km/h,2
    However, when I open the controller and go to adaptions these fields are not listed at all, to even try changing them.

    What have I missed? Do I need to login first? I haven't been able to find a code yet.

    My scans are posted here.

    Please post an auto-scan.

    Have you checked other modules involved for any adjustable adaptations?

    His scan is here in the Reference Scans section.

    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.

    That's puzzling. I can't think of any reason why something that shows up in a map wouldn't show up when you try to access it directly.

    You have posted Adaptation maps, from something that is not in the Autoscan of your car (from a MQB Model):

    SW:5Q0-980-653-G HW:5Q0-980-653 --- Frt Sens. Drv. Assist

    You have this for Address A5: Frt Sens. Drv. Assist (R242):
    SW: 8W7 907 217 A HW: 8W7 907 217 A

    Aarghh!! I got my files mixed up! Sorry! That explains the discrepancy. It was from a TT I had for a couple of days.

    That still leaves me trying to find a setting for the switch on / off speed.

    I will have to remove my autoscan post too, and sort out the correct files. Can't believe I managed to do that!
