Thanks. That is quite a list and includes issues I have been unable to get addressed for over 2 years.

Does Audi just install these updates at request or do I need to specify the update and cite an item or two? I have a USA 2020 Q8...thanks!

I went in only for an oil change and got the updates, so I think they update at the 1st opportunity. I was never notified of the updates though.

It will show as an outstanding service campaign and when you book in for a service it will be noted for updating at that point.

Also, on mine, there were 2 updates; the MMI and another software update.

Sometimes Audi will come out with updates that remedy multiple issues.
I just had the 91X4 on my 2019 A6 at West Covina Audi this past Saturday (4 days ago). I now have a buggy backup camera. Several times when I put the car in reverse, I either get a completely black screen (including the small distance sensor overlay), or I get JUST the overlay and the MAp screen remains on the main window. This has happened several times (not always) since the update. One time I put the car back in Park then in reverse again and the camera worked.

Are you hearing any noise about this?

Yes, my scenario exactly.
I read through the list of fixes and will benefit from many.

Was that by chance the 37M6 'recall?"
I see in another threat this addresses the lag in acceleration for a start/stop/start event. Glad that was addressed!

We had an issue similar after the MMI update. None of our camera's were working and the car was throwing errors about the pre sense and intersection assist being unavailable. The dealer had to update some other control module to clear the errors. Got it back Friday and seems to be working properly so far.
