So post app update, I've had 3 sessions where the car charged to the required percentage I set (80%), apparently stopped and I wound up with only 1 notification. This is in contrast to the myriad of notifications I and many have had prior to the update. So the app appears to be fixed, but what about the charging issue that apparently started it?

I say that because on 2 occasions, my % SoC read 79%, not 80%, and the 3rd time it was 80% as per my charging limit. So the 2 times it went to 79% gives me pause that the issue isn't really fixed, but only the app's notification are. If the charging issue was fixed, I'd think the car would show 80% every time, especially if you observe the state of charge only an hour or two after the session ended. The e-tron doesn't appear to have phantom drains like Teslas.

The issue has been the car reaches its 80% limit for the session and then for some reason it quickly reports back it's now only at 79%. That starts the charging process again until it reaches 80%. That sends out a 2nd notification. The cycle goes on and on until you've told the charger to stop. The number of notifications you receive tells you how many of these cycles occurred. Many have seen 25 or more of these notifications, meaning there were 25 or more brief charging cycles. This behavior has actually been observed during these cycles by some who were there to see it. In other words charging really does start, stop, start, stop at it cycles between 79%-80%. I haven't personally observed it since my charging takes place in the early morning hours.

My real concern is the multiple quick on & off charging cycles and the wear on relays and associated equipment involved in the starting & stopping of these sessions. Now is it possible that the entire issue has been fixed? It might be, but again to have 2 of my 3 post-update sessions show 79% in the morning, gives me pause. I stop the charger at 5am, so I don't see the cycling and can't confirm this behavior.

I'll probably wind up doing this during the day so that I can first-hand if this issue is fixed or just masked by the app fix.

Another reason to lease over owning.

Nah, I don’t see it that way. If the problem still exists, and I’m not sure it does, it will be covered under warranty. I used to write off leases when I was working, but now that I retired, I prefer ownership.

Many pros & cons to both the leasing and ownership approach.

But I’d like to keep this thread on track and not have it devolve into a lease vs purchase thread. :)

So, are you using the Audi Timer to set up the charge with Cabin Conditioning enabled? If so, then the SOC you observed might just be due to the time you check it. When Cabin Conditioning is running, the SOC will drop about 1% as the cabin is conditioned and then the battery sips from the wall to go back up to full SOC and then repeat the cycle. I've gone out to my car when this is going on and see different light indicators depending on what the car is doing.

No, actually I've never touched the car's timer at all. I use the ChargePoint Home Flex for all timed charging. So there should be no preconditioning going on. That 1% drop must be due to something else. The only way we'll see if this 1% drop & cycling is still going on is to sit in the garage when charging just completes and the charger is still allowed to charge. Does it still actually charge & stop, charge & stop after the initial completion? I suspect it's easier for Audi to have simply made an adjustment to the app to notify once regardless of what happens after that first notification.

The harder part is getting the car to stop cycling between 79% and 80% or whatever % is set under 100%. At 100% the issue doesn't exist. My assumption on this was always that the car itself would have to have a software update to stop this. The app could have easily been taken care of by Audi in Germany as they apparently did via the app update that occurred.

I have a 2021, and have never gotten the multiple alerts. Also, If I look on the charging history for my charge point charger, it only shows one charging session each day...I am assuming if the car was cycling the way the app notifications would suggest that someone with a charge point would see multiple charging sessions each day.
