Alternator OEM Audi or Duralast

Just bought and installed a Duralast Gold from Autozone last week for my '07 9-5. It has a little whine at 2500 RPM but works better than OEM. Has a lifetime warranty and it's 100% new too!

My 19 c8 3.0 had the same exact issue within 4 months of buying it last year. And the car died on me mid fwy in dtla. Take it in to ur nearby dealer theres an open recall on the alternator i believe.

Might be a coincidence, but those lights all came on about a month before the Electical System: Malfunction light came on in my 2021 S6. They replaced my battery and alternator.

When my alternator failed in my 24v, I replaced the alternator with a duralast, replaced the harness and fuse panel with OEM parts, and 50k later it's still working like a champ.

I want to hear an opinion on getting a duralast alternator and popping it in my n52 I have heard very mixed things about these parts some work fine others are trash.

Rs6 definitely has an alternator issue. I’m currently at 25k on oem alternator.

I got a alternator from AutoZone( duralast pos) and a new battery , same thing, car started with new battery ,voltage at the battery was around 12.5 and voltage directly on the alternator was the same exact voltage as the battery which showed the alternator still wasn\u2019t charging I took that alternator out got my money back and went to a reputable alternator and starter shop around my area and got a quality rebuilt one. They tested the alternator before they gave it to me and confirmed it was in working order. I installed it and still the alternator is not charging the battery , i checked voltage directly at the new alternator and still got the same voltage as the battry while the engine was running , so its still not charging the battery or producing power

Believe it or not, though I installed a brand new alternator(Duralast gold) that turned out to be bad from the start and I had to replace it again(so I guess what I’m saying is check the tention on your belt, but don’t rule out the new alternator as - also - being bad), been 2 years since tho.

I purchased a Duralast 115A Alternator 14921 (remanufactured) which, once we moved the pulley and fan from old to new, it mounted up without a hitch. Once the battery was charged I connected everything up and she started right up. However, the voltmeter was hanging around 12V so we put a multimeter on the battery and only saw 12V+/-.

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.
