Q8 Prestige Plus 3.0L

  • Automatic transmission
  • 19,000 miles

A D V E R T I S E M E N T S

I purchased a used 2019 Audi Q8 Prestige Plus, with Sportline Pkg on 9/7/21. Car had approx. 18,500 miles. The car attempts to shut off when decelerating at any speed below 3000 rpm. There is also a significant throttle delay between the time you push the gas pedal and when the engine responds. To be clear the car is in Dynamic mode and the Start/Stop mode is deactivated. It appears that under certain conditions the car is trying to determine if it should shut down or continue running.

The Audi 37M6 update has been performed on my car which was supposed to correct the problem. The Audi Knoxville Shop Foreman drove the car and experienced the problem, contacted Audi Technical Assistance center (case# HS-822562) and was told that the car had the latest software correction. The Shop Foreman wanted to erase the transmission clutch adaptations to see if the car could relearn the shift process but was advised by Audi Technical Assistance not to erase the transmission clutch adaptations and would not allow the Shop Foreman access to the car software in an effort to resolve the problem.

Note: there was a class action lawsuit in May 2020 for this problem that was dismissed because the car manual states the car can experience a delay when restarting from the Start/Stop mode. However, my issue also occurs when the Start/Stop system is turned off. At this point I have avoided 3 different accidents, When the car is decelerating at any speed and below 3000 rpm it tries to shut off, and when the gas pedal is pressed slightly to accelerate there is a significant delay in when the car responds. There is no continuous throttle response below 3000 rpm with the Start/Stop system turned off.

I was given a 2021 Q7 with a 2.0 as a loaner car while my Q8 was in service and I did not experience any of the issues I I have with my Q8. Based on all of the similar posts I have seen on AudiWorld forum, this is a major Audi issue and they are trying to avoid a major recall. Issues have been filed with the NHTSA but they fail to act because there are no reported deaths. I was advised by my dealership to also write a letter to Audi USA as the dealership acknowledges there is a major problem and they want to try fix the issue but will not be given access to the car software to troubleshoot the issue.
