Hi, yes i replaced the 12V battery and the fault code disappeared. the dealer told me it was because I have not been charging the car often enough and especially during winter the 12V battery was really struggling to stay alive haha. Hope this helps sorry for late reply.

same happened to me after washing my car as hybrid battery had 0% charge.mine still reads no faults after visiting local garage. got my battery replacement booked at audi for tomorrow so ill let you know if that resolves it. Funny how car works normally as long as the hybrid battery is topped up.

i got the same error code this morning but my car seems to be driving fine. tried using OBD scanner but issue didnt show up. Please let me know what main dealer says if u do get it checked
