Conrad668s Posted November 3, 2022 Share Posted November 3, 2022 Hi, Had my 2016 allroad for nearly 3 weeks and get occasional engine light with my cheap code reader displaying U0029 Regular mechanic can't get any further with his diagnostics and recommend taking to Audi. Anyone had experience of this code? Cruise control doesn't work and it won't do a regen on dpf either. Using loads of diesel. Google says NoX sensor or canbus issue Quote Link to comment Share on other sites More sharing options...

evopilot Posted January 22, 2023 Share Posted January 22, 2023 defiantly a Nox sensor issue, that car cant talk to the sensor for whatever reason The easy one is check the sensor is not dead after that you looking at checking the wiring unfortunately which is a right pain Quote Link to comment Share on other sites More sharing options...
