    Please switch on dipped headlight warning VW Golf 7.5 UK Model ???

    Hi guys, hoping you can help with a few suggestions. My car has a really annoying light assist function which is way too sensitive for my liking and wondering if there is a way to delay its operation as evening/daylight approaches. As the light begins to fall, a message appears on my Digital dashboard to switch on the dipped headlamps. While this message is displayed, and until you actually turn the headlights on, no other settings or displays are visible in the digital cockpit any longer. This is really frustrating as I drive quite a bit in very slow traffic at dusk/dawn and don’t want to have my dipped headlights on when I don’t need them, in particular in almost daylight conditions !!

    I have looked in the 09 Central electrics module and channel map attached. Did a lot of converting German into English from there, and eventually found and played around a bit with the default lux settings I found (dumped below fyi) but it made no difference to the functionality of this dipped headlight warning at all regardless of trial changed values.

    MAS08228-ENG133434-Light sensor-Daemmerungsgrenze: Hysterese_obergrenze 1200 lx
    MAS08228-ENG133435-Light sensor-Daemmerungsgrenze_Hysterese_untergrenze 2200 lx
    MAS08228-ENG133444-Light sensor-ECE_Lichteinschaltschwelle 0 lx
    MAS08228-ENG133433-Light sensor-Einschaltgrenze_CHO_LHO 600 lx
    MAS08228-ENG133437-Light sensor-Helligkeitsgrenze_Licht__einschalten 1200 lx
    MAS08228-ENG133438-Light sensor-Helligkeitsgrenze_Licht_ausschalten 2200 lx
    MAS08228-ENG142232-Light sensor-HMI_exterior_light_sensitivity frueh

    Assume its controlled by the slave HLRS coding in this channel, but could not find a deactivate option in there either.

    Wondering if anyone has any knowledge of how I might be able to delay this warning till much later, (the vehicles head units “Late” option is also selected), but still the warning to switch my headlights comes on in almost full dayligh, or how to just deactivate the warning completely.

    Owen: It's very interesting (at least to me) how length of twilight period varies across continents and time-of-year!

    I'm not sure that a solution to your problem is immediately obvious, but it will be illuminating (pun intended) if you post-up a complete (meaning unedited) auto-scan for the car in question (instead of just the Gateway installation list).

    Again, I'm not sure about your mk7.5 - but in earlier model mk7 Golfs, the upper nibble of Byte 0 on the light-sensor (which is a LIN slave module to the BCM - so the sensor is not included in the gateway summary list) had a bunch of software switches that enabled earlier switch-on thresholds for the sensor. Since you haven't posted a complete auto-scan, it's not possible to ascertain whether the light sensor on your car has one of these earlier settings selected.

    This can be disabled by changing the adaption channel "ENG141656-ENG126818-Außenlicht_uebergreifend-Fahrlichtwarnung_Hinweis_Konfig" to "not active" in your BCM.

    Am I the only one around here who thinks it's absurd that this car would tell the driver to turn on the lights, rather than just turning on the damn lights? I means it's not like those lights aren't under full digital control!

    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.

    Thankyou very much for this TBAx, I will give this a try tomorrow and let you know if it disables the switch on warning completely.

    Not, if the rotary light switch is set to 0.

    Hi TBAx,

    Tried your suggestion and it worked, disabled the warnings completely. However, I decided to choose one of the alternative setting options for that channel, “Hinweis_in_LDS-Stellung_Null” rather than the German option of "not active" per your recommendation. What this setting allows is for the warning to come on with the light switch in the 0 (Off) position only, and if I then briefly switch to Auto or Headlight setting with the rotary light switch for a few seconds in order to allow the dipped beams to come on, and the warning to go off, I then move the rotary switch to side light position only, and the warning remains off. So this is an ideal workaround for me, thank you so much.
    For my further learning, I would be interested in finding out exactly which channel adaptations control the daylight sensor on/off thresholds for this dipped beam warning message and functionality. I know the trigger is via light senor on the rear of the interior mirror, as I have held my LED torch up to this and watched the warning message switch off on the dashboard. Further observed this through watching the advanced measuring data values changing in the following two channels as I moved the torch up to and away from the mirror sensor.
    IDE05838-MAS04809 Light recognition sensor-Darkness - On
    IDE05838-MAS04810 Light recognition sensor-Request for light activation - On
    With the torch against the senor, both values above changed to Off. Moving it away they both change back to On. (Car in low ambient light garage)

    The perfect solution for me would be to modify the low light trigger value(s) in the appropriate channel or channels, assuming there are some linked and related settings around this. (Hysteresis settings along with Lux light level settings etc.) If I could adjust this so that the warning does not come on at all in other than “appropriate low light levels actually requiring dipped headlights”, I would do that and revert the ENG141656-ENG126818-Außenlicht_uebergreifend-Fahrlichtwarnung_Hinweis_Konfig setting you suggested, changing it back to Hinweis_in_LDS-Stellung_Null_und_SL per the vehicle default and VW’s intention I guess.
    If you could add any more clarity around that aspect it would be very much appreciated, if not though, no problem as your suggestion has provided a very workable solution for me on this very annoying “switch on dipped headlight” VW Golf MK7.5 light problem.

    Best regards,

    Owen

    Owen: Thanks for the heads-up. Yes, if anyone knows these answers, TBAx is definitely the one!!.

    Sounds like you have a passion for solving this problem and the intellectual capacity to pursue the matter - both excellent attributes.

    In the primordial recesses of the last century when you were probably not born, a wonderfully kind and well respected teacher here in the Antipodes tried desperately to instill lighting theory into the stubborn minds of his students (of which I was one).

    Although I suspect that the definition of twilight is a physical thing involving the relative position of the sun and the earth's surface, from a lighting perspective we used a standard of 500 lux in his classes. Because I was more interested in "extra-curricular" pursuits in those days, I'm not sure if this measure was a recognized standard (I suspect not) - but it's a not unreasonable rule-of-thumb metric IMO.

    So - back to your problem: If I look at my database of BCM admaps on an application like MS Access and if I apply a search vector for settings around 500 lux, the following adaptation channels are returned:

    ENG122932-ENG123007-RLS_Night_Sensitivity-p_lx_rs_dawn > 200 lx
    ENG122932-ENG123006-RLS_Night_Sensitivity-p_lx_rs_day > 500 lx

    Now - without any knowledge what-so-ever of how the boffins @ VW/Audi actually intended these channels to operate, I'm guessing that there is an inherent hysteresis built-into the design for the headlight ON/OFF function. By which I mean that in order to stop the control mechanism from "hunting" (i.e. stopping the switching ciruit from continuously cycling on/off around a single threshold light value) 2 x threshold values are used.

    This means (and again, I'm guessing) that assuming that the ignition is kept switched-on, once the headlights are automatically enabled at the ENG123008 value of 500 lux (above), the control mechanism will stay switched-on until the ambient light level rises again to the ENG123007 value of 200 lux - see pic below:



    I've not tried playing with settings on either of the 2 x channels above - but I believe that they are sufficiently intriguing for your purpose as to warrant your attention. Perhaps?

    Don

    PS: and just in case you are wondering why I launched into a discussion about switching hysteresis - if you are successful in modifying the setting on the ENG123006 channel - you might consider retaining the same differential that is designed into the factory settings . By which I mean if you lower "day" level - increase the "dawn" level by the same amount

    PPS:... and here is another aspect of the ability to alter the switch-on light thresholds - alas in the wrong direction for your purpose (it's the long-code string for the RLS/RHLS/RFLS). Notice that the code-string value is the same as in your auto-scan. It would be interesting to see what happens to the Lux settings in the 2 x adaptation channels above if the threshold settings are changed in this Byte ?
