How about these three measuring blocks?
Found them on the Gateway 19.

IDE09074-MAS08256 Vehicle properties-Max energy content 18750 Wh
ENG106155-ENG118436 EM_prcSoh-SOH_P 74 %
ENG106155-ENG118435 EM_prcSoh-SOH_Q 75 %

Interesting. Can you tell us about this vehicle? How old? How many kms?

Interesting indeed... here's mine, build date 6/15 with 20,500 miles/33.000 km:

I have been "babying the battery" charging only to 60% since I don't use the car for my commute and drive it only 13 miles most days.

Mine is an 2014 model, with 90 000 km on it. I live in Norway so it runs in cold climate.

My friend has an new FL 300 km 2018 model so I invited him over to check his car and it states only 75% SOC_Q and 75% SOC_P.
Both our cars spend the night outdoors in -10`C so that leads me to think the battery temerature is effecting this reading.

How many Watt Hours or kWh is shown when you check in Max Energy?

Well, OK, maybe a newer Rev of your App on your smart phone will turn something up later that makes sense.... that looks like hexidecimal code that hasn't been deciphered yet.

I am using VCDS 18.9.1 (newest release).
Anyhow, not sure what to make of these readings.

Will report back when the weather is warmer, right now its -10`C. And Sunday it will be close to -20`C.
Its hard to be an EV owner at this time of year ;) Less than half the range compared to summer time.

You may wish to occasionally charge to 100 and drain to very low, as batteries do like to use their full capacity sometimes to maintain their health
