It took me some many hours to find Your post. I updated radar now in 2 cars. First car I used Online, but now that I've found Your post I don't need it anymore.
Thanks!
To Be Honest I don't really understand what the issue is here.
If the keys were replaced using "New Identity" then it can be that FeC-s weren't restored properly.
What I see with ZF8 gearboxes is that after ECU flash gearbox starts to behave weirdly. Weird shifts, weird timings etc...
Gearbox flash itself is usually fine. It's the ECU that need preDieselgate SW.
