The crazy thing is I called them 2 hours before to tell them about the malfunction warning and they didn't show any concern. I called them a second time when the car warned me to pull over safely. Still no big concern to them. they just scheduled me a appointment for the following week. 15 mins after talking to them the second time my car lost all power. Every warning light imaginable popped up before it stopped. I had to get a rental because the shop was closing when I got it towed there. Was told today they didn't have a loaner for me. I hope they get one soon.

I was on a long distance trip when it happened - but thankfully it died near an Audi dealership. Symptoms lowered like everyone else had indicated. It started with an electrical system failure and progress to a complete shutdown of the vehicle within 40 miles.

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). The system failed at about 37,500 miles on the odometer. Similar symptoms as yours.

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

Thanks.

Replacement of 48V alternator with 3rd generation unit 4NO 903 028 P costs me 2400.-EUR. It clearly states that this is production/design failure if there is 3rd generation unit. Normally it should be replaced under warranty conditions but unfortunately warranty for my car was ended. They gave me 10% discount for material and labor costs + now I have 2 year warranty for this replacement. Still I'm really happy with my choice for this A6 petrol modification but this mild-hybrid failure was unnecessary surprise.

But so far, I have a $3000+ repair bill to look forward to. I was forced to buy a third car this weekend (Porsche Cayenne) since Audi won't provide a loaner car!!!! 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!!

You took a risk (We all did) with a 1st gen model, and then decided not to buy extended warranty, and now you're blaming Audi? Come on.

There is no recall as others have said, just a TSB.
