Exact thing happened to my vehicle earlier this month. Left me stranded. Luckily I was in the last month of warranty and got a shiny new alternator!

Last year I had a similar experience/warnings with my 2021 RS6. Flat bedded to the dealership and they replaced the alternator under warranty.
Pros: replaced under warranty
Vehicle:
Audi RS6
Mine lasted 270 000 km before needing to be replaced .
Pros: long lifespan
Cons: eventual failure
Vehicle:
Audi A6
Mileage: 270000 km
I will always vote for a 10SI or 12SI GM alternator swap on an L-series engine. Affordable conversion bracket. 1-wire GM alternators are simple, reliable, cheap and readily available online but not easy to find in parts stores. 3 wire GM alternators are are easy enough to wire up and are absolutely everywhere in parts stores if you’re more concerned about parts availability and potential breakdowns on long adventures.
Pros: simple, reliable, cheap, readily available
Cons: 1-wire not easy to find
I used an Audi B6 alternator in my TDi Touareg. I could have repaired it but it was cheap enough to buy. It's an easy job too.
Pros: cheap enough to buy, easy job
Vehicle:
Audi
My shitbox, I replaced my alternator just for my window motor to go bad, I replaced the window motor just for the thermostat to go bad the next day, it’s inevitable.
Ya my alternator failed in 32k kilometers... But Audi Japan replaced it for free so it was okay ...
Pros: replaced for free
Cons: alternator failed
Vehicle:
Audi Q8
Mileage: 32000 km
Wouldn\u2019t recommend unless you like spending your time on the side of the road or at the dealer. Mine just went back to my local dealer today for its 4th alternator in 32k total miles, 3rd one in the last 6 months. Literally just got the car back 5 days ago for the same issue.
Pros: Fun to drive
Cons: unreliable, frequent alternator issues
Vehicle:
Audi
Mileage: 51500 km
Had an alternator problem (which was a recall) that completely shut down the car in the middle of driving (dash and all electronics turned off) leaving me stranded to wait for a tow truck. Audi fixed it for free.
Pros: Audi fixed it for free
Cons: alternator problem, shut down car
Vehicle:
Audi A7
Die neueren Generatoren sind heute noch Müll (Haltbarkeit). Musste ich erst in meinem A6 erleben (der zu meinem Glück noch auf Garantie ging). Im RS6 gehen die Dinger auch am laufenden Band flöten.
Cons: schlechte Haltbarkeit, häufige Ausfälle
Vehicle:
Audi A6
