1-2% voltage difference is not bad and don't expect it to be perfect. I have seen mine being 0.01V off after rebalancing but that does not affect the DCFC speed. I had read a Taycan document that said the BMS triggers rebalancing if the inballance is more than 2%.
I also prefer to stop the...
You don't have to drop SoC.
I have tried with both draining and topping the battery and then leaving it undisturbed.
I have seen the battery cells rebalancing only on the top (95% in my case then leave unplugged 10hours). I have done this 3 times and I have seen it working using carscanner...
Charge your car to 95%. Then unplug and leave undisturbed for 10 hours to balance the battery.
I bet this will solve your problem. I had exactly the same issue as you 3 times and this resolved it.
Car Scanner is a mobile app I bought from the app store. It connects to the car via a Bluetooth OBD2 device you can buy from amazon like this one https://a.co/d/07erJJxy
When in the app, I look for the cell with highest and lowest voltage. Ideally they should be the same, but sometimes they get...
Yes It happened again at least twice. The fix is easy.
Charge to 95%, unplug and let the car parked undisturbed for at least 10 hours. That helps rebalance the battery cells. I have taken measurements via Car Scanner which confirm the battery degrades to big cell voltage imbalances and this...
Your observations are spot on. The estimate is fixed if I switch to Guest account and totally wrong if I switch to my account.
You are also right, this started around the same time as weird SoC drops and very slow DC charging due to battery cell imbalance which I resolved by charging the car to...
Mine shows I will arrive with more SoC than when I departed every time even with no charging stops

The new software does not prevent the sudden and unexplained SoC % drop. My car has the update and it suddenly lost 4% while parked.
It also does not remove completely the white Assistance system unavailable warnings. I already had two after the update...
Update after having this installed for 9 days. I have experienced two white warnings and LCA was not working at one trip after the update. The car was clean so that was not the issue. So much for that being fixed..
The car lost 5% while parked for 5 days. The loss was mostly sudden after the...
It has happened to me twice. Try closing and opening the side mirrors. https://www.macanevowners.com/forum/threads/lca-unavailable-fix.22375/

The only module version I can retrieve from Carscanner is for the CAN Gateway. This screenshot is after the update. I didn't capture before. If someone can provide before version we can compare.
Just call your dealer and ask what campaigns are open for your car and then ask them for an appointment to get them performed. It is free under warranty.
I picked up my car after this update. LCA (blind spot) was not working on the way back. This is the second time it has happened to my car right after picking it up from the dealer. I believe their car wash messes up the mirror positions. I have found a TSB that describes a fix by closing and...
