[/QUOTE]I also had the nox sensor issue. Replaced both upstream and downstream sensor. The car was fine for 5 months, then the upstream nox sensor failed again. Its no need for new software after replacing the nox sensor, but the learned values / adaptations for scr / nox must be resett. After the secound nox fault at my car, i reprogramed my ecu to NO adblue / nox. So my car runs without adblue, and nox sensors is inactive. No other tuning, like more power and such.. ONLY adblue / nox off. Its wonderful to get rid of it
Hi! Sorry for the off topic but I also haf Adblue and Nox isolated, but 300 km after that I have dpf soot sensor failed. Did you also made DPF off, because my mechanic said it is a MUST to delete dpf with adblue and nox.
