That's equivalent to 2.16 miles per kWh. Assuming you have the original e-tron with 86.5 kWh usable battery capacity, your current efficiency predicts 187 miles of range at 100% on a fully functional battery which is reasonably close to what you are seeing on the GOM. Your GOM is showing 87% of the range you would expect to see based on the app (162/187), but the app is showing you the average of an entire segment whereas the GOM could be biased toward the latest part of the segment.

Given Audi's poor software functionality, I think there is a 0% probability that Audi can remotely control your vehicle's charging limit and show you 100% charge in the vehicle if it's really only charging to 80%.

checking my app for the drive yesterday, it's reporting 46.2kWh/100mi. A little worse than the last couple road trips, but not so out of line I suppose. I was pushing it a little fast yesterday, cruising around 80-83
what you should be getting is based on your current battery capacity (which is battery degradation and temperature dependent) and the way you drive...cruising around 80-83 is not going to be range friendly at all.

my guess is that your current battery capacity is around 80 kWh and with your driving efficiency ~2 miles per kWh you should be getting around 160 miles of range with full charge.

hay, thanks for posting and reviving this thread.... reminds me to update.

yes, I kinda knew that driving those speeds isn't the most efficient. The thing is though, I've had this on quite a few long road trips and have driven these speeds before...so speed is not really a new variable.

incidentally, on the return trip home, I was keeping a hyper-close eye on consumption rate vs range. I found that on that day, driving about 80 was the speed at which my GOM range held steady......I was comparing the delta between range to destination and range on the GOM. Above about 80 the delta reduced, below about 80 the delta increased. Cruising 80 the delta held steady. I found that interesting.

And my update is that the day after I got home and recharged, I've checked then and a few times and my GOM number divided by state of charge has been checking to be back up to just under 200 miles where it always has been. Right now, for example, 92 mile GOM/0.48 SOC = theoretical 191.7 miles at 100% SOC
I don't know what.....but something very odd happened to that GOM and SOC indication algorithm on my trip

I wonder if they uploaded different software for 93U9. My long-term efficiency over 20k miles was 2.7 mi/kWh on the stock Goodyear Eagle Sport tires. A few days after the recall, I got a new set of Pirelli Scorpion AS Plus 3 in 20" which Consumer Reports rated highly for low rolling resistance, then reset the long-term counters. 200 miles later, my long-term efficiency is 2.6 mi/kWh with the new tires, but the GOM dropped to 152 miles at 80% instead of the usual 170 miles+. I'm confused as to why it's nearly as efficient as the worn Goodyears, but the GOM has dropped so much.

If the battery module needs replacement, the dealer will order the necessary parts requiring replacement. I'll also have the car checked for tsb#93 21 40 2060814/3 as well. Mine is showing 117 mile of range at 72%.
Took my 2019 EO in today for 80,000 mile service. Was told the recall affected my vehicle and I agreed to go ahead with it and take the loaner for a day or two. I was told the same thing, if the testing came back normal, they would schedule follow up in 4 months. Otherwise cells/modules may need replacement and it would take a week to get parts.
My range has also been around 125 miles at 80% in the morning, around 35°F ambient, after charging L2 all night.

I had a 2019 etron quattro for 3 1/2 years. 125 mi at 80% at 35F strikes me as low.

I am in DC and in our few sub zero days this year my '19 e-tron was getting 167 miles first thing in the morning with preconditioning. If no preconditioning, then 140's to 150's. Once 60's popped up the 176 to 185 GOM returned.

Sounds like my GOM is low.
After 93U9 testing they report no anomalies, but I'm going to ask about the TSB today.

Long delay, apologies! That's what they said they replaced (high voltage battery regulator), and whatever work they did involved some work under the hood. I'm not arguing because after a month of steady driving I went from 156 max to 210. My habits and the temperature have changed slightly, but not 35% improvement. Before anyone criticizes max charging, I don't charge to 100% often but I'm taking a long trip tomorrow. Only posting this in case it can help someone out there.

At 8.7kWhr you are not hurting that battery, but the one thing you should do is set your departure time so that it hits 100% right about the time you leave. Oh, and pre-condition the cabin whilst hooked up to ‘Shore’ power also.
