I had my car inspected by my local Audi specialist garage, the drive system fault errors were related to a turbo under boost issue. Unfortunately the garage were unable to recreate the fault but recommended to change the MAP sensor as that was the first error appearing. 100% solved the problem. My car is a 2019 Q5 2.0 40 TDI Sport.
Hi,
I also have a 2019 Q5. What did you find was the issue in the end?
I'm experiencing the same symptoms over the past few days and hoping it was something simple and inexpensive!
Fingers crossed!
