Range very low for state of charge

[Fluff]

I've recently had something similar, went on holiday for a week, UK temp was 0c to 5c. When I came back, range has been 200 miles or less. its now 2 weeks, and range is now increasing, currently 250 ish.

According to my findings what appears to be the extra range comes from the SoC % discrepancies. Normally,for this to happen you must also get extra +% SoC readings.If it's not the case then most likely the calculations giving you the first lower range was based on a more aggressive driving style/road conditions/temps/weather.If the latest calculations are based on factors more favorable to range it's logical to see an increased range.
The only reliable reading we have available is kWh/distance.And based on this one alone we can actually realize if there's an error on the SoC % and how off its indications are.For my last 1000 Km I was suspecting there must be some 15-17kWh somewhere missing and because such an amount of energy is very much to be considered just "lost" somewhere I decided to perform the procedure I described as accurately as possible.All my calculations were based on kWh/distance traveled in relation to what the charger was reported it was delivering to the car for a certain charging session. Every single time,especially in long charging sessions there was this 15-17kWh gap as the car reported it received more energy than it actually did.
If you have similar problems and suspect erratic/false SoC % behavior, when you are at very low SoC,especially below 20% you'll certainly see the reading go up considerably when the car remain unused for some hours or overnight.And this will continue all the way down to 2-4%. I'm considering it like I'm taking back my debts from what the SoC % indicator have "stolen" from me.There wasn't any energy lost at all after all...it was just remained hidden inside the depths of the battery cells,invisible from the SoC % system display.

Don't know if such a behavior could indicate some kind of feature problem with the car but at this stage I really don't think there's indeed something wrong with it.The system must somehow "remember" its battery capacity boundaries.It reminds me of when a window looses its memory and stop moving prior reaching the lowest or highest point in the door frame.By pressing and keep pressed the window button at both the extreme ends of the movement the system "re-learns" where to stop correctly.
In a similar logic (although not so oversimplified) same counts here too.Procedure is drain as much as possible down to 1-2% SoC.Leave it there for several hours until no additional values appear.When finally stabilized leave it alone for at least 13 hours,24 would be best I believe.AC charge it slowly up to 100% (max 11kW charging speed).After 100% is reached unplug it for a while and plug it again, however don't use the app or the charging screen in the car because it might not initiate the charging process as it will "think" it's already fully charged.Try using a public charger instead and initiate the charge directly from the charger provider app or by using an RFID card for the charger.Monitor how much energy you will get.After fully charged the 100% will be the real one and the range will be more realistic but you have one more think to do.Leave the car at its real 100% for at least another 13 hours,24 will be better once again.After this you'll be good to go and enjoy again your "stolen" range and take advantage of your vanished kWh!!

Hey,

do you notice when you unlock your car it shows a higher range say 150 miles, but then when you start the Macan it says a lower number like 120 miles. Is this normal?

Yes,I have noticed such a behaviour but not every time.I would say it happens approx 50% of the times I take the car for a ride.I feel it's likely normal to see small differences however the 30 miles you describe it seems to me quite a large difference.Mostly I see a difference of around 15-20 max 25 Km.

I also see this problem, I usually charge up to 80% and during the winter I have noticed my App and car generally report around the 200 miles, however when I select the transmission to move off it generally drops on the dashboard screen by at least 10 miles or so. I also noticed that for the first few miles I am only getting about 1.6 kWh rising to 2.3 kWh throughout the drive. In all I love the car but the range is extremely disappointing and may eventually make me change back to petrol assuming they are allowed to make them.
