Alternator OEM Audi or Denso

If the alternator is OEM, replace it, because is close to the exhaust manifold, it will fail sooner than later.

If you are replacing the alternator, strongly recommend using only Honda dealer sold remanufactured alternators (probably Denso) or an aftermarket Denso brand remanufactured alternator. Lots of problems reported with other brands.

If you’re gonna go through the effort of replacing the alternator, do NOT get cheap shit. Get a new/remanufactured Denso alternator.

Denso alternator is my go to choice for that vehicle.

For my personal vehicles, I replace alternators at 100K with Remy or Denso new alternators and have never had an issue and I save a lot of money by waiting a couple of days.

Nippondenso (Denso) is what I would choose, I believe this is the OEM manufacturer.

I would get Denso

Had the same issue with a reman denso alternator that went in a Honda, it was the cheap diode/rectifier pack that was fitted that was causing the bat light to stay on.

I took the alternator apart as well, but it's quite worn and a new one does not cost a fortune, so it's not worth it to refurb it.

my local garage replaced with an aftermarket. Two weeks ago the squeak of bad bearings arrived and *it* had to be replaced. A different mechanic (Honda specialist) said OEM parts were very hard to find, even here in Los Angeles, so they installed a better aftermarket alternator. That was a squeaker. Then they installed another: squeaker. Now I'm waiting for the delivery of a Denso alternator from Texas that's arriving on Friday. $100 more but I've got my fingers crossed.
