Hello folks, I have a question. Since "US Style Turn Lights" app not working on my car, I'm trying to activate US Style Parking Lights by coding but I'm not able to.
I tried codes that written at this thread (https://forum.obdeleven.com/thread/8710/interesting-users-adapting-leuchte-channels) but It didn't work on my car. (Maybe because it's 2017, or because it's S3, I really don't know...)
What I want is US Style Parking Lights with %30 brightness. (I have led turning lights)
And secondly if possible, I want to control it from mmi as on this video (I've already activated DRL ON/OFF switch on the MENU)
Thanks!
EDIT: Leuchte 0 BLK VL B36 >> Lasttyp 0 is not active
so I think that it's not possible to do it, am I right? Thanks.

hmm......... yes, I suspect that you are correct. The link that you provided in your post about how to alter the Leuchte-sets in the central electrics module fundamentally assumes that the central electrics module controls the lamps in the headlight fittings. This is a good assumption for lots of MQB platform cars (like your S3) - but the assumption falls-over when high-end lighting is installed in the car (like "LED turning lights")
When a MQB platform car has high-end lighting, it's normal for the lighting functions of the central electrics module to be reduced and instead for these roles to be transferred to separate modules known as Light Control Modules (LCMs). When this happens, the Leuchte-sets in the central electrics module will be disabled as factory-settings
You can check if this car has LCMs by looking at the SCAN report. If LCMs are installed, the SCAN should have modules similar to this:
39 Light Control Right System description: LCM_MLBevo Software number: 8V0907399D Software version: 0014 Hardware number: 8V0907399D Hardware version: H08
Faults: No trouble codes found
29 Light Control Left System description: LCM_MLBevo Software number: 8V0907399D Software version: 0014 Hardware number: 8V0907399D Hardware version: H08
Faults: No trouble codes found
