The instrument cluster has failed per the recall 90vc. Audi issued the recall for every model made in 2021 with the exception of the a3 and A4 and I believe this was a mistake as my instrument cluster has the same failure.
I have a 2021 Audi A4 that is also being affected by the instrument cluster failure/recall. My model , A4 was not included but I am experiencing the same failure and this was reported to the dealership. An online search will show just how many people have issues with the instrument cluster. The instrument cluster screen just went out while driving. I have to monitor my functions via the app on my phone. The dealer wants to charge me full price when every other model in 2021 has been recalled for the same issue. The A4 should be added to the instrument cluster recall for 2021 Audi.
