I tried some of your adaptations and they didn't work in my 2016 TSI. I couldn't find the turn signal delay ones - I found something similar (optic feedback something) which had values of 'Decelerated' and 'Normal'. Changed it to 'Normal', but didn't notice any difference in the turn signal timing. Maybe it's because I have dynamic turn signals, not sure.
I also tried the DRL indicator in the cluster, which is super useful, but also nothing lights up on my dash. I checked with a flashlight and there doesn't even seem to be any light there designed for it which is odd. I remember my Audi A3 8V (2013) had an indicator for that.
I assume things are different on the SW
