Engine light with error code U0029 in Audi A6 (C7) Forum Posted January 4, 2023 On 11/3/2022 at 8:47 PM, Conrad668s said: 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 Hi did you ever get to the bottom of this fault ? I have same issue with a q7
