Only getting 172 miles after a full charge?
 

When I first picked up my car at the dealer it was fully charged and stated it had 202 miles of range available however since then every day when I get in the car and it is fully charged to 100% the available range displayed is 172 and 168 with AC turned on.
I have only been able to get 57.5/100 kw/miles and the long term best average was 43/100 kw/miles which is pretty bad the car uses double what my i3s get. Why doesn't the car return to 202 available miles once completely charged?

Because the car figured out your consumption and according to that it calculates your "real" distance :

Battery real capacity is only 84kWh which is multiplied with your 2.0mi/kWh consumption, you get 168 miles range (84*2).

The car is trying to best estimate your range. However, this is almost impossible to do since it doesn't know how or where you are going to drive. To make estimates it is using your driving history. In your case, your driving habit is below the range estimated when you picked up the car. I've noticed that there are huge variabilities in projected range. Some factors include your speed (if you go fast on the highway range goes down fast), how fast you accelerate (hard acceleration uses more battery), whether or not you let regeneration slow you down (puts more power into the batteries), how much stop and go you do (every time you accelerate is potentially decreasing your range), etc.

BTW, I think your consumption statistics are wrong. No way is it 2.0/100 kw/miles. You probably mean 2.0 miles/kwh? If you were displaying kw/miles it should be something like 45/100.

Finally, if you connect up to the Audi app you can see consumption data on a per trip basis. This may help you understand what's happening as you can see which "trips" are more efficient.

Crazy consumption the last five trips listed in the app are as follows

55.4 kWh/100miles 48 miles driven avrg Speed 30mph

55.4 kWh/100miles 26 miles driven avrg Speed 17mph

43.5 kWh/100miles 14 miles driven avrg Speed 14mph

43.5 kWh/100miles 14 miles driven avrg Speed 14mph

59.5 kWh/100miles 4 miles driven avrg Speed 12mph

57.5 kWh/100miles 23 miles driven avrg Speed 19mph

Sorry you are correct Ill edit the post

Try charging the battery to only 80% maximum for the next 100 miles and you should see the range increase. The reason is that because you charge to 100% you are missing a lot of potential recuperation energy (I remember Audi saying that more than 70% of the used energy will be recuperated) as the battery is too full.

The speeds are low and the temperature is probably ideal, but I assume you climb a lot of hills in the SF area?

here are my last few trips from the myAudi app ( which are inline with what is reported on teh dash)
38.1 kWh / 100 48 mi driven avg 43 mpg duration 1:07 h
36.9 kWh / 100 25 mi driven avg 35 mpg duration 0:43 h
35.6 kWh / 100 20 mi driven avg 40 mpg duration 0:29 h
44.6 kWh / 100 25 mi driven avg 32 mpg duration 0:46 h

Not really its a very flat commute Oakland to the city I would say 20% hills 80% flat driving. The eTron is just a thirsty beast. Im fine with its range for nearly all my driving as its mostly 100 miles a day or less it's a shame I would probably need to stop and charge it if I just did a day trip to Calistoga...

What is your charging target % set to? Mine was set to 80% by the dealer or factory. At 80%, mine charges to around 170. At 100%, it's been more like 220. Check your setting.
