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.
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.
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.
Mine lasted 270 000 km before needing to be replaced .
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.
My audi B5 will absolutely refuse to use anything but OEM for the alternator
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.
My vehicle had this issue and they said it was because there was a bad batch of batteries in some of the models which was causing the alternator to fail. I had several issues with this vehicle around 50k miles such as failed alternator which was replaced because of the warranty but this should be a recall!!! Very dangerous and unreliable.
Ya my alternator failed in 32k kilometers... But Audi Japan replaced it for free so it was okay ...
