I've read multiple treads about this, and none seem to have the leuchte settings to accomplish this. I have a 2019 S3 with the auto light sensor.
Currently the car does at night CH/LH low beams and during the day just a blinker wink.
I am trying to configure it to have DRL ( LED daytime running lights ) on in both daytime and nighttime when CH/LH. I was also looking for DV52's file detailing different leuchte settings and maybe attempting to figure it out however haven't had success.
Has anyone been able to accomplish this ?

So, what you are describing as not-operating is the Coming Home (CH) function
What currently happens on this car if you do this:
CH - Switching-ON
- Switch off the ignition.
- Operate the headlight flasher for approximately one second
- Open the driver door
The Coming Home lights should switch-on when the driver door is opened. The switch-off delay starts when the last vehicle door or the tailgate has been closed.
CH - Switching off: - Occurs automatically once the set switch-off delay has elapsed.
- Occurs automatically if another vehicle door or the tailgate is opened within approximately 30 seconds of it being switched on.
- Turn the light switch to position 0.
- Switch on the ignition.

Hello Don, The coming home function operates correctly. As per factory settings, what I am trying to accomplish is to modify the lights that come on during the CH/LH feature. Instead of having the low beams activate I would like it to be only the DRLs. Currently these are my options on the MMI And the options on OBDeleven are the following I would like to add DRL to coming home leaving home function. And have them be the only lights that come on when I unlock the car aka leaving home. Thanks, Guy

Guy: OK - I understand better now (I think). To do this, you need to keep the settings in both of your screenshots and then add the Leuchte-commands for CH/LH to the Leuchte-sets for DRL and finally you need to turn-OFF CH/LH the low-beam Leuchte-sets (with the same Leuchte-command). Notice that I use both "CH" and "LH" in my response above. An important aspect of this tweak is that there is only ONE Leuchte-command for these functions and it applies to both CH and LH. So whatever mods that you make, it will apply to both light functions -not just CH. Is this acceptable? If you want to proceed, I prefer to see how the Leuchte-sets on your car are programmed (because they have tended to vary in past cases). But you only need to post-up the Leuchte-sets on ONE car side. However, I need to see ALL 19 x adaptation channel settings for each Leuchte-sets) The other important confounder with this tweak is that it will ONLY work if the DRLs on this car are controlled by the central electrics module. Some vehicles use separate Light Control Modules (LCMs) to operate the lamps in the headlight fittings. If this car has LCMs, changes to lamp behaviour are NOT possible, alas. Please post-up screen-shots of these Leuchte-sets:
Low-beam: Leuchte6ABL LC5
DRL:Leuchte2SL VLB10 and Leuchte4TFL LB4

Hmm.......... I suspect that this car might have LCMs (alas) because screenshots for the 2 x DRL Leuchte-sets aren't programmed as DRLs. Can you post-up a SCAN for this car to confirm my hunch. If you are not familiar with the process of digitizing your SCAN reports -click on Garage tab at the bottom of the OBD11 home screen - then select the car - then select History - then follow the instructions below.
You don't need to connect the OBD11 dongle to the car for this process because you are accessing historic data that lives in your OBD11 account
When you receive the Email that you sent to yourself, include the contents of ONE scan in a new post

Arrhh................yes, just as I thought!!!
Notice these modules:
39 Light Control Right System description: LCM_MQB Software number: 8S0907397D Software version: 0022 Hardware number: 8S0907397D Hardware version: H07
Faults: No trouble codes found

Faults: No trouble codes found
Alas the existence of these modules in your SCAN means that the headlight lamps on this car are NOT controlled by the central electrics module. And importantly OBD11 can NOT access coding in LCMs
So, bottom line= the DRL behavior can't be changed on this car!!

That’s what I suspected when I posted the scan. Thank you very much for looking into it Don !
Appreciate it,

dv52 (Australia) let me riddle you this if I shall... I just bought a used 2017 S3 (USA). My right control module is faulty and my right DRL doesn't work. I bought a new one from China, hooked it up, still same fault. The leds were fine on the old module, didn't look burnt. So I don't know what the issue is Since there is no way to program the LCM's, can you think of any solution to disable the left? I either want to fix the right one, so they both work, or just disable both of them. Aaron

You say "I bought a new one from China, hooked it up....." - my response assumes that you mean that you fitted a new LCM rather than exchanged the entire right-side headlight fitting.
Without intending any offense - my problem in answering your riddle more accurately is that this is a Yankee car!! Again, sans intentional malice in my response - cars sold in the land-of-the-free are built differently to those in markets on the rest of this lonely blue planet. As a self-confessed ignorant man who happens to live in the very, very, very deep South - it's always been a complete mystery to me why stuff works differently in USA - but clearly it does! So for me, the unexplained enigma remains up there with other unfathomable and equally profound questions (like the meaning of life - the answer to which isn't "42")!! OK- enough of the levity! With my earlier caveat about NAR (North America Region) models being different and purely from the perspective of diagnostic logic - there is an abundance of intelligence in your findings after replacing the right-side LCM. Whilst I would have preferred to see the actual error descriptors in the SCAN report before/after the exchange - the exercise obviously proves that the DRL fault in this car is elsewhere!
Now, Ive been doing this stuff for a very long time and I'm a firm believer in Occam's Razor (look it up). So following Mr Occam's technique, having discounted the LCM as the "perp" (to use a USA colloquialism), the next obvious culprit is one of the components in the headlight fitting!
I don't share the implied conclusion in your words " The leds were fine on the old module, didn't look burnt.". LEDs rely on a totally different mode of operation to incandescent lamps; the latter type lamp uses a heat process - but LEDs produce photons by exciting electrons in a semiconductor junction from one valence-shell to another. So, notwithstanding that LEDs also get hot, the amount of energy consumed by LEDs is significantly less.
This means that failed LEDs normally don't look "burnt" - in my experience, their visual appearance doesn't change at all (normally)! The only way to tell if an LED has failed is via a "diode" test with a multi-meter - but this test requires access to the LED leads. As for your specific question, my response is I'm not sure that you can disable just the DRL function on a headlight fitting that uses an LCM !!! As you are aware, no coding changes are possible on LCM fittings -so variations from factory operation aren't possible (alas). Nevertheless, with the proviso that I'm making lots of assumptions and more than a few guesses about the actual equipment in this car - here is a typical set-up for the DRL components internal to a LED headlight fitting (note the diagram is from a non-NAR car):
As a totally untested suggestion, I guess that you could try disconnecting the wires on pin #11 and pin #12 on the 14 x pin headlight connector for the left-side headlight fitting (on the car-side of the headlight loom - I suggest).
Traditionally, these are the DRL power-supply and DRL signal wires from J519 (which is the central electrics module in OBD11 speak) that tells the electronic-smarts in the headlight assembly to turn the DRL-LEDs ON/OFF. I'm guessing that removal of these wires will disable the DRL function without affecting other lighting functions in J860 (hopefully). However, disconnecting these wires will generate error codes from the hex09 module - so expect these fault messages.
Again, my suggestion is intended as an experimental option for you to try - it's not a proven answer to your question !
Don
PS: Of course, another option is to try swapping the J860 modules between the right and left side fittings (it's called "J861" on the right-side fitting), If the DRL fault follows the swapped car-side, the problem will be in the module rather than being the physical LEDs inside the right-side headlight assembly!
