Alternator OEM Volkswagen or Duralast

The Duralast one looks to have a lifetime warranty.

Been running a duralast in mine for about a year no problems.

Been running a duralast in mine for about a year no problems.

The high rev voltage must be over 14 volts, so if not, then its the alternator. But make sure all connections clean and greased.

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.

IMO duralast doesn\u2019t last no where near as long as a good quality Bosch/Denso 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+/-.

Wouldn't recommend AutoZone based on my experience. Had a duralast gold fail on me and had to get a replacement one.
