We have a brand new e-Tron and it's been a nightmare! On our first full day with the vehicle, I charged the car overnight, and the car showed charging complete with a range of 230 miles. We drove 63 miles that day, but the range dropped to 31 miles. It was a very scary drive because the range was dropping so fast--two or three miles coming off the range every eighth of a mile for much of the drive, and we had no prospect of charging. Luckily, we made it to our destination. But, things kept getting weirder. Audi advertises that the battery charges fully in 100 hours (or about 4 days) using a normal household outlet, which is all we had available. After eight days, the car is stuck at 139 miles of range, and says "Charging ended"--so the vehicle won't accept more charge. We are very nervous about our return trip tomorrow because, if the car loses mileage like it did on the way here, we will end up in the breakdown lane with no power at all. We also tried charging the car with 240v, and it still says "Charging ended" and won't take more charging. Obviously, our car is going straight to service as soon as we are back home, but just curious if anyone else has had these kinds of battery problems and what I should be sure to ask the dealer before taking possession of the car again. (Note: driving conditions have been around 50F, some rain, no unusual weight. The range decreased the fastest on a long, flat freeway driving 67-70MPH).

It's impossible to say whether the battery meter is incorrect or the battery has an internal problem. Would be advisable to see if there are any Audi dealers near you as you travel back home just in case the range drops to near zero. Driving after zero miles have been reported to end up in the car being towed to the dealer. Shame to have this kind of a problem right away. Hopefully Audi corrects the problem and you go on to have a great experience with the vehicle.

Not that you probably have set the advanced charging settings, when you turn off the car you can navigate to that on the mmi screen “Adv change settings”. Make sure that the screen (swipe to left to get to second screen of info) that shows what level the car considers fully charged. You can adjust that level down from 100% and that could be one possible problem.

As for rapid range depletion, do you live in a hilly area? We are in Seattle and it’s got streets up to 20-23% grades and just a few blocks will knock of 3-5 miles of range.

That said I’d agree with the other reply. Take it to the dealer. But there is a dirth of information there too is what I have found.

The charging system for this vehicle is quite complex. I just purchased a 2021 etron sportback and noticed that the charging level was going down with each charge at level two. I think I figured out that the computer in this car is smarter than we are. I've done a few experiments because it was my suspicion that the car was judging the range by the way I drove. So I changed my ways of driving a few times to see if that affected the charge. Well sure enough it did. When I brought it home it was charged at 240! Drove in about 90 miles and then it only charged to about 205! Took it out again and then drove about 70 mi and it charged at 199! I realized the conditions I was driving and how I had the car programmed. I noticed that when I took it up to "all road" put the heated seats on and was on a straight away and used little breaking whether it be the paddle or the break the mileage charging that night came down considerably. When I was on local streets breaking going between 35 and 40 miles an hour the charging increase by about 20 miles that night. What I deduced from this is that the number of miles the car charges after a day of driving is what the car has determined would be the number of miles you would get out of a charge driving the way you're driving. Each experiment that I did resulted with the same theory. So what I suggest, if you want to get your car back up to full charging take it out on a 50-mi run put on your cruise control don't gun the engine and then drive for about 10 mi using your brake which regenerates and charges your battery as you hit the brake. And then when you bring it home and charge it I'm 99% sure the car will have determined that your way of driving affords a higher charge because it is determining that you are driving in the most economical way possible! I suggest keeping your speed between 60 and 63 mph on cruise control when you're on a straightaway. Don't gun the peddle! The day before I did the final experiment I was charged at 205 took the car out for the day and put about 102 miles!! Came home put the car in on a level 2 charge and in just 6 hours at my home the miles have gone up to 235! I truly believe that these electric cars are made in such a way to conserve as much energy as possible by forcing us to drive a new way. We have seldom think about the mileage and how we drive when we have gas stations that are 500 feet away from one another because we always know that we can stop and fill up whenever. Electric cars make you think and plan something we're all not used to and are learning to get used to. Hope this helps and I'd be curious to know what the results are if you try what I've suggested above. Good luck!! Audi wasn't able to give me an answer so I figured it out on my own! Always drive in EFFICIENCY MODE!!

@Mrs Jet said pretty much what everyone eventually concludes, the previous rate of energy usage is used to forecast what the likely range will be if you continue to drive as before. However, the experience you had from receiving the car is not normal (unless it’s a used car with some history we don’t know), so check the maximum charge level slider. I think you’d expect somewhere between 140-180 miles at absolute minimum (depending on ambient temperature and driving style), not 67 miles.

That's not true! I've done several tests and the conclusion is based on data! 3 days in a row I drove between 100 and 130 miles on a full charge at 205! Put it in EFFICIENCY MODE and kept speed at between 60 and 65 mph! Heat on 72⁰ and radio on full time! Beginning of the trip 30-40 mph for about 5 miles with stop and go and regenerative brakes charging the battery at all stops! No gunning the car except to get onto an entrance ramp for the highways! Came home and plugged in my car while milage was down to the level I discussed from 205! Both times I am recharged at 235 miles and last night 238! I conclude my hunch is right and you should try it! The computer is evaluating your driving and letting you know how many miles are expected with the amount of energy you're using! It does that so that you won't run out of charge while expecting to get 235 miles when in essence you're burning more electric which could leave you stranded! I will continue to update as I'm keeping a close eye on results!! 😊
