There are quite a few TSBs associated with the 48V system. As I'm not able to physically diagnose, here are a few:

I loved this car but AUDI needs to step up to the plate and fix this issue I smell a class action law suit on the horizon!! I have owned Audi cars for 15 years but this experience is not what I expect from a luxury car manufacturer. I'm trading in this car for a Subaru as soon as possible!!
Is the A6 a Prestige? Other level? Can you provide the manufacture date on the door frame? My date of manufacture (A7 Prestige, S-Line) is Sept 2018 (09 18) according to the specification sticker on the driver's door (not the door jamb or pillar).

Let me know what your model, trim package, manufacture date and mileage are and we'll have more data points.

They have had it for three weeks and the only think they can tell is that the parts needed (alternator, 48 V battery) are on backorder and they have no idea when they will come in.

Fortunately, the car is under warranty so the loaner is covered but this experience has me thinking I should sell it before the warranty runs out (one more year). Anyone else experience very long delay times with their Audi or is this a one off?

hi bro did you mean you had to replace both the alternator and the 48v battery?

Hi mate, I believe on the C8 A7 forum you were asking about a TSB on the same subject. Look at post #21 in here and the last link shared had the TSB information. Good luck!

My son has the same car as I do, a 2019 A6 Premium Plus with 3 liter engine. He too had a total failure. Car was under warranty and dealer replaced the alternator and the 48v battery in about a week. In New Orleans, LA.

Same thing happened to me (September 17, 2022). Car has been with the dealership for about 2 months now. Anyone have an update on when the parts will be available??
