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.

So is my eGolf from 2015, just crossed the 90Kkm mark. I'm interested in how I best can read the SOCP/SOCQ values from my car as well and at what value(s) one possibly could claim the battery warranty for broken, eg. is it below 70% of what 24.2KwH or 21-22KwH something...

Any hints are appreciated, TIA!

Edit: Got a VCDS cable now and am seeing various numbers for these:

ENG106155-ENG118436 EM_prcSoh-SOH_P
ENG106155-ENG118435 EM_prcSoh-SOH_Q

in the ranges 87-91% after now +93Kkm and 4 years

IDE09074-MAS01078 Max Energy in the range 18600-18700kWh

Also find interesting stuff in the 8C Battery Management Systems like how much energy in cars life time I've put into the battery/car and how much has been pulled from it:

IDE01036-MAS01375,Højspænding / Hybridbatteri: Historik data 1-Tæller til amperetimer: ladning,52893.730, Ah
IDE01036-MAS01376,Højspænding / Hybridbatteri: Historik data 1-Tæller til amperetimer: afladning,-51711.761, Ah
IDE01036-MAS01377,Højspænding / Hybridbatteri: Historik data 1-Tæller til kilowatttimer: ladning,17605.365, kWh
IDE01036-MAS01378,Højspænding / Hybridbatteri: Historik data 1-Tæller til kilowatttimer: afladning,-16977.790, kWh

divided into the driven range one can find so far the overall efficiency of the car: 93198km / 16977.790 kWh ~ 5.49 km/kWh
