Definitely more obscure on this model with a lot of the settings in German. I have a 2015 S4, and don't recall anything in German for it.

sorry its been awhile since I logged in

I got a few PMs about coding for DRL, I only tested it on HID headlight equipped A3 with Etron DRL (not sure about LED matrix headlight)

I am not sure what VCD other people are using but here is what I did (assuming you have some experience with VCDs already)

you need find your DRL adaptation module under (09)
Right DRL module is RB32

1) change the following - basically it re-programs the LED DRL light module with a secondary function
- primary function AB is DRL - dont change
- secondary function CD as parking light so that it stays on when you turn on the headlight
- leave EF GH function untouched
- change the following

RB32-Lichtfunktion C 5 to "standard light"
RB32-Lichtfunktion D 5 to "parking light"


2) set LED DRL intensity to max when it is being used as parking light under CD (the value can be 0-127 but the DRL LED only has on or off state or either 0 is off or 127 is on)

RB32-Dimmwert CD 5 to "127"


3) repeat for Left DRL by programming module LB4 using similar value.

you can use the same idea for parking lights but in reverse if you want to turn off parking light when headlights are on with module VRB21 and VLB10
