Alternator OEM Audi or AC DELCO

I'm showing a new acdelco 135amp alternator for roughly $163 plus shipping through rockauto.

Acdelco is oem for GM. They make high-quality parts, never been disappointed by one.

ACDelco makes a brand new alternator for $95. They were the OEM for GM.

I went with RockAuto as well, but went with the AC Delco Gold Reman that was wound to have 135 Amp output instead of the OEM standard (~110 I think) I want to say it was around ~$170 with a $45 core deposit. AC Delco is a solid name in parts, and I believe was reman'd in Mexico.

I used an Audi B6 alternator in my TDi Touareg. I could have repaired it but it was cheap enough to buy. It's an easy job too.

On that list, I'd only go with the AC Delco.

Well, I'm late to the party, my alternator failed today at 45,000ish miles. Oh, and 2 months after the warranty expired. The silver lining is that my buddy owns a shop that works on Audis.

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

I got 3 AC Delco remans from RA before they refunded my money and refused to send a 4th...The third they sent arrived fine but lasted 37 miles on the car before the front bearing locked up. Over a month of headache and ended up buying a Tuff Stuff alternator.

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.

I've just got this issue in my Q8 in UK. I kept telling my service centre about the alternator but they said no recall. Going to give them an angry call tomorrow since car dead. Luckily have extended warranty, rac quote is \u00a33K!
