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.
The vehicle at 13,xxx miles on the high ways, and during stop & go traffic; vehicle begins to tremble, transmission and floor shakes, rpms are higher than normal, abnormal noises coming from engine (screeching), jerking on acceleration on the first gears, rough idle, happens only on highways after 1hr of driving. Can drive over 40 min without any check engine light turning on. No codes come up, while clearly having issues. After a day of being off, car goes back to normal without those issues, just vibrations and pulsing on idle. -happens on texas highways where vehicle begins to have trouble with acceleration and transmission shakes yet no check engine or error messages appear. -problem has been shown to one Audi dealer while happening and another Audi dealer was able to reproduce the problem. They even noted how vehicle will do all the issues noted above while not providing any error codes or messages. - vehicle has been inspected but all they do is reset software and hand back keys. While issues are still prevalent. - no warning, no over heat or any codes appear on the vehicle. Issues started at 13,xxx miles. Only on long highway or stop and go traffic does it happens.
The reversing image occasionally appears white screen phenomenon during the process of reversing, the reversing screen suddenly turns white and cannot see anything behind, which brings danger to the driver and others, causing danger to life and property. Apparently the dealer didn't take this seriously.
