hi vcds can't do it, it has to be a more advanced odis device
Hello! I have an Audi Q3 2020 from the USA. I need the original coding (adaptations) file from VCDS. I cannot activate the rear fog light and the dynamic turn signal on the fender mounted lamps. Tailgate turn signals are working properly. File from my read attachement.

Did the dynamic turnsignal conversion on my a3. VCDS is all you need, and a couple off cables..
1 pin on all taillights needs to be connected to 12v allways on.
My a3 is a pre facelift and had 4 wires from bcm to indicaters on taillights.
The facelift has 2 wires. (only left and right) There i needed to make a connection between inner and outer indicators..
VCDS:
I also needed to turn off the non connected pre facelift wires in coding.
At last you need to put the led indicator output of the 2 remaining outputs on 127%. Why: 127% means no dimming.Strange enough.. (14,4v :127% = 12v :100%) The dimming causes the dynamic part of the lights to go out of sync.
Extra: While your working in the bcm: Put the revers lights on 127 too. The RVC sees a flickering image is on 100%
For the fog lights: Are your factory usa light with fog lights? Couse these are not difficult to find in the wireing..

Hi
Would have been better if you started another thread for A3 turn signal. But thanks for sharing
