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.

*BUMP*

Any new takers on the coding for the DRL?

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

Thanks for the instructions. They are a little vague, but I was able to find where to change the settings. However, there are no exact options for "standard light" or "parking light." Most of the options are in German too! Can you check and let us know what the exact options are from the drop down menu? Thanks!

I was not trying to be vague but every VCDs tool is different, there is no single instruction tnat works for all tools.
seriously if you dont know how to code, you should find someone who know. You can screw up your lights and make sure you backup all the steps you have done so you can go back to stock config.

FYI I dont speak german - depending on your the VCDs tool you are using, here are some of the translation.
standard light - "Standlicht allgemein" or "Standlicht allgemein (Schlusslicht; Positionslicht; Begrenzungslicht)" or "Standlicht vorn"
parking light - "Parklicht rechts" or "Parklicht links (beidseitiges Parklicht aktiviert li & re)

trying to help other Etron owners, I dont want to hijack this thread to become coding help

the number "5" has to do with the position of the light in the car - RB32 has a value of "5". LB4 has a value of "4" by default you cannot change it
ie: Leuchte4TFL LB4 - basically means "light4 is LB4"; Leuchte5 TFL RB32 = "light5 is RB32"

once again if you don't know how to code - be very cautious coz you can screwed up your light function.

this is my snapshot for adding parking function to DRL LED strip for LB4

Leuchte4TFL LB4-Lichtfunktion C 4>Standlicht
Leuchte4TFL LB4-Lichtfunktion D 4>Parklicht
Leuchte4TFL LB4-Dimmwert CD 4>127
Leuchte4TFL LB4-Dimming Direction CD 4>maximize

backup first!!!

Wong...thanks for the replies. My apologies...I guess we need clarification on which system/software you are specifically using. In your OP you mentioned VCDS, which I assumed to be the most favored by Audi enthusiasts...the Ross-Tech VCDS. However, this may not be the case as that's what I use and had trouble following your instructions initially. I will give it another shot this weekend with the additional details you provided.

Regarding VCDS modding, IMHO you do not need to be a coder to use it. I am far from being one myself (finance). You just need to be diligent in following the instructions, document your changes in case you need to reverse them, or as Wong mentioned...backup before making changes. This is my 3rd Audi and I've used the Ross-Tech VCDS on all of them. The e-tron is different as it has some settings (actually a lot) in German, which I do not recall my prior 2 vehicles having ('10 Q5, '15 S4). And the e-tron community is so small it's difficult to find information sometimes. I'm mainly on Audizine, but came here as e-tron owners are pretty non-existent over there. They don't even have a dedicated forum section for the e-tron!
