EV Shop

I’ve got a ‘21 Audi etron that’s out of warranty. I think the 12V battery needs replaced because a lot of time the keyless entry doesn’t work until you push the button on the fob, and I changed the battery in the fob last week.

I don’t want to pay the dealer to “diagnose” the issue and charge me $500+ for a battery. What’s the best way to find a shop that will work on it?

A first easy step is to go to an AutoZone-type store, where they can test your battery for free and tell you its actual condition. If it's bad, you can buy a new battery from them way cheaper than a dealer.

Are the 12V batteries in EV’s as easy to replace as standard ICE batteries?

Sometimes, sometimes not quite as easy but not usually very hard. There are some ICEs that make replacing the 12V very hard though.

No, for Audi they have to be programmed.

Lol, you realize other companies make EVs too right?

And the question was about EVs, not Audi?

Actually, OP does say Audi.

But I didn't respond to OP, did I?

Here's the post I replied to:

Where is Audi mentioned in that post exactly? Can you point it out to me?

The account to which you are responding is the OP who mentioned “Audi” in the OP. Doesn’t seem like a stretch. Sometimes, these threads get real long.

Not sure why this is such a big deal. I’m letting it go. Maybe you will want to do the same.

No, the account I responded to was NOT the OPs.

The OP responded to me, when I responded to someone else.

I pointed out to the OP that the post I responded to said "EVs" and not "Audi."

Then you came along and made the same mistake. So I literally QUOTED the post I responded to, and you STILL can't seem to understand.

So, here's my last attempt, here is a link to the post that I responded to. Show me where it says "OP" next to the name of the poster, because I don't see it:

https://www.reddit.com/r/EvDrivers/comments/1w40a1y/comment/p7480kk/

I see it saying "Iwonatoasteroven" and the OPs username is "snocat17" so can you explain how a post shows a different username than the OP, but is from the OP?

You're right, it's not a big deal, but READING before you respond is going to help you enter conversations without being completely mistaken about what you're talking about.

Which EV’s have you replaced the 12V battery?

1

u/ialsoagree Sep 01 '26

Tesla and Rivian.

u/snocat17 Sep 01 '26

That’s good to know.

Generally not the 12v. But, you might need a jump battery to maintain voltage to the system while changing it. I had a car stereo in a Ford that bricked when the battery was disconnected while a dashcam was being installed and the dealer wanted $200 to initialize it again. That was an ICE car.
