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
I posted here https://www.macanevowners.com/forum/threads/destination-soc-estimate-more-than-departure.22405/
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...
Are you sure the campaign code does not exist in US? My US dealer confirmed campaign code WSJ0 (VR28.13) shows up for my car and I have an appointment to get that applied next week.
I asked my dealer to pull the list of open campaigns for my vin and this update was in the list together with some others (seatbelt clip, rear axle harness)
I have seen SoC going up several times, e.g. charging stops at 80% and I unplug and next morning SoC is 83%. In all these cases the ambient garage temperature and battery temperature dropped. So probably the change in SoC is due to temperature change.
I have also observed the reverse, stop...
Your dealer did a good job with the diagnosis and recovery.
Their diagnosis confirms my suspicion and the data from Car Scanner app that shows the issue is due to battery cell imbalances. It also means there is a bug in the Battery Management Module that lets the cells get to this state.
Next...
It is probably a variety of reasons, GPS sigal loss is one that is documented in a TSB.
I also had LCA unavailable once and that can be due to mirrors forgetting their position and the quick fix is to close and open them. This is also documented in a TSB.
CAN bus issues are also likely.
Same as...
You are not alone, it is a common issue and I believe it has something to do with the car being parked in a garage without good gps signal or the car shutting down its computers to save power and thus losing the signal...
