Hi

I got engine light on and fault code U0029 Sensor /Hybrid CAN Bus, and i can´t reset it.
Any idea on how to find the problem?

Please post an Auto-Scan for context.

PS: Moving to New User section. Since the question is about clearing a fault, it does not belong in General VW/Audi Repair. That section is for questions that do not involve a scan tool.

We have no idea what car you have or how it is equipped, so we need you to post a full unedited VCDS Auto-Scan using the English version of VCDS.

This code means no CAN Bus connection to sensors, in this engine you only have a NOx sensor on CAN Bus. I had this code it was no connection to NOx. Unplugged connector.
