1. What does Intersection assist: fault. Please contact workshop. mean?

Audi identifies this as an intersection/lane-change assist malfunction message. Official Audi technical bulletins say the affected assist functions may be inoperative and instruct workshop diagnosis.

2. Technical explanation

This is an Audi OEM alert, not a standardized OBD fault code. Audi service-bulletin evidence links the message to an inoperative intersection/lane-change assist function. The same bulletins also list related warning messages for Side Assist/exit warning, rear cross-traffic assist, and, in one bulletin, Audi pre sense. The supplied evidence does not establish the specific failed component or root cause for an individual vehicle.

3. What system is affected?

Intersection assist / lane-change assist. Audi bulletin evidence references lane-change-assist control modules J769/J770 (address words 003C/00CF) and a radar-sensor control module, but does not establish which module is faulty on a particular vehicle.

4. How serious is this code?

Unknown. The verified evidence confirms an assistance-system malfunction message, but does not assign a severity level.

  • Intersection/lane-change assist may be inoperative.
  • Official Audi bulletin evidence also associates this condition with possible messages for Side Assist and exit warning, rear cross-traffic assist, and Audi pre sense.

6. Possible causes

  • Not yet established by verified evidence for an individual vehicle.
