So i Owen 4 Audis RS7 2019, RS Q8 2021,RS 4 Cab 2008, A4 2018. So oi am a devoted Audi Guy, however my RS Q8 has been in the shop since May 10th 2022 and it is due to an Alternator issue. I have been waiting for this part for months. Is anyone else having issues with Alternators???

I had the same issue, was internationally back ordered. I ended up finding one on eBay - as I was able to find the exact part number for my 2020... I lucked out, someone had it on the shelf. I'm out of warranty due to my APR tune, so I ended up saving money going that route.

My dealer told me, I could pay a $200 rush fee to get 'in front of the line'. You should ask your dealer if they will do the same, if you don't mind paying the $200.

Good luck.

For everyone else, there is a TSB for this, sounds like the alternator we get from OEM is no bueno.

Is this just on the RS or SQ8 affected as well?

I wish that they offered an expedited service. I would gladly pay the 200.00. Believe me I have asked to speak to anybody in corporate and they just tell me to call the Audi care line

This seems to be a known issue on the 48 volt Alternators there is a RS6 waiting for one at me dealer along with mine.
Service said they have replaced a few already
does anyone know how to find the exact part number on the unit

I had the same issue last month.
Dealer allocated a new one in 2 days. Another day for installation. Horrible experience with the Alternator...

Does anyone know if any errors were generated by this failure? I had multiple faults a few months ago in the MMI after I was idling for a bit in a parking lot and the start/stop system cycled about 5 times. I got the generator failure, active differential failure and a bunch of other warnings. After turning the vehicle off and on again, everything went away,

When I checked OBDEleven today (several months later), the only thing I found was below. There was no date or other information. I am trying to figure out if this is a precursor or early indication of an impending failure. I am planning a pretty long road trip in a few weeks, and don't want to get stranded

Hey everyone, I unfortunately had all these issues, you can look at my posts in the “electrical system malfunction” thread. But I have a Q8 prestige so not an S or RS but the alternator is the same on all these models.

I had an error come up on a Saturday so I made an appoint with Audi on Monday. And what they found was that my alternator went out and because it went out a few days before I could take in it and drove it the 25 miles to Audi. It from the 48v battery flat and once you drain a lithium battery flat there is a high probability it will never fully charge again. This was my case and it wouldnt charge past 11%. Had to get a new alternator and 48v system. The alternator was on back order for a couple weeks. Worst part is that my Q8 was at like 58k miles and the whole costed me 7k-8k.

I have a handful of private shops around me that specialize in Audis and non of them wanted to touch this issue. Hope this helps you guys out with this info!

My generator went out 10/11. I was told that it would take 14 days to come in. Got a call from service department on last Friday and was told that my part was stuck in Customs. Dealer had no idea how much longer it would be. Sounds like Audi should put a recall on this

Looks like my dealer wants to replace my in tank fuel pump instead of the alternator (2-3 weeks). I explained to him about getting shutdown on the freeway and they still insisted it's a failing fuel pump. Not super excited about it.
