Electrical complaints
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.
The main instrument cluster is not stable- it tries to start up then crashes. As a result, speedometer, rpm's, gas tank gauge, etc are not available while driving. The screen displays blank with a red triangle, tries to start up then crashes again. This seems similar to Audi recall campaign 90VC, but for some reason the A4 was not included in the recall, but I'm having similar symptoms with my A4.
