Well got the car back finally after several weeks. And it turns out they only changed the fuel pump. I don't know whats going on at my dealership but I've heard the story change and now it's back to fuel pump which they claim caused the shutdown.
On top of that, they washed my car despite me requesting it not be washed and now I have crazy swirls all over on my full PPF. Car looks like it's 10 years old now. Not a happy customer. Have to go back to get my finish rectified.
Well, exciting to find my group - people with this weird "generator" problem.
2020 Q7 Premium Plus (more than 40,000 miles but less than 50k miles)
October 19th electrical issues escalated quickly and resulted in me with inoperable car on side of highway
October 20th service person said they would look at car and have it ready by end of the day; end of day called and said that it would be an extended repair and to come pick up a loaner
Picked up loaner new Q5 with 1,000+ miles and was told 1. Q7 needed a generator 2. part would come from Germany 3. there were 60 of these on the way to the states 4. there were 250 people in line in front of me
So, today has been 49 days. I have taken the Q5 loaner in once already to have the temporary tags replaced (expired 10-31). The pre-sense on the Q5 has almost caused accidents twice when turning from the inside lane across oncoming traffic. I have been back to the dealership another time getting more things out of my Q7 that I never expected to need.
Dealer says that they (at this point) still have no idea on a timeline.
2019 Q8 owner here. I have not had the same Electric System Malfunction as you all (yet). Does anyone have an idea if we can check if our vehicle has the affected part before the problem happens? Can the dealer tell if our alternator is an affected one if brought in?
I've read the TSB which looks like it was released on 3/2/22 and it states "The software needs to be updated in the starter/generator control module" . Since I purchased my Q8 used in May of 2022, is it possible that the update was already applied by the Audi dealer I purchased from since it was after the TSB release date?

that is one of the things i was getting at. we know the new part number. and it lists parts that were superseded. if someone can request the old generator back, we can get a part number from the old unit, i think. maybe there is a better way though.

Or look at the part number on the new unit, if it's viewable. The new part is the "P" version. I'll check for it on my vehicle this weekend, since it was swapped and reprogrammed in April under warranty.
Problems with the alternator occur not only in the Q8 but in many Audi models with a 48V installation.
As far as I know, this is a problem resulting from faulty 48V battery charging module software.
And here is the OEM number of the alternator:

I am experiencing the same as everyone else on this thread. Back on October 19, 2022, I received the Amber Electrical System Malfunction light and immediately called Audi to schedule an appointment to bring it in. I was told to bring it up there the next day. On October 20th and around the corner (1 mile away) from the dealer, light turned from Amber to Red and shortly after, dashboard looked like a Christmas Tree and car completely shut down and had to be towed to dealer. It was confirmed to be the Alternator and I was told it was on back order and would be approximately 1 month. Fast forward to today, December 10th, Audi still has my car and can’t provide me with an ETA on when it will arrive.
My patience is diminishing. Supply Chain issues or not, if they can’t repair their own vehicle in a reasonable timeframe, that is insane; I basically have a lemon at this point. To add salt to the injury, I purchased this vehicle as as CPO back in July 2022, so I barely got 3 months usage out of it before this issue came up. I‘m contemplating telling them to buy the vehicle back because I refuse to wait 3+ months for a part to come in. I was told they have a vehicle that has been waiting 6 months, yet they have newer Q8s coming on the lot. Luckily, my car is at 46/47K miles and they gave me a 2 year extended warranty on top of the original warranty, but it leaves a bad taste in my mouth. I owned a 2013 Audi A6 for many years prior to upgrading this year and NEVER had a back experience but this is making me reconsider. I’m seriously thinking about taking legal action against Audi USA because this is insane and if their supplier can’t produce for whatever reason, they need to find a backup supplier who can. I’m paying on a car that I can’t even drive PLUS they put me in a Q5 Loaner - a downgrade. Very frustrated with this all.
I agree w @retom that the issue is originating in the battery charging module software - if you read the TSB, that's essentially what it says.
So, I speculate that if you get the battery charging module software updated, you shouldn't ever have this issue - but you may need to lean on your dealer to get them to do this as a preventative.
I wanted to look up the alternator parts to see if the part versions in the cars have been superseded, just to see if there might also be a alternator issue - and it doesn't appear they have, except with the Q8. However, since the SQ8 and RSQ8 parts aren't superseded, I don't think we can draw the conclusion that the alternate is part of what is causing the failure. Plus the records people have provided show the new part number that are going in as replacements as matching these part numbers.
The diagram of the SQ8 part makes it look so different from the other two. I don't know why that is, maybe in reality it looks the same, but I do not have my car yet so I can't check.
