i3 "charge time increased" message
Discussion
We have an odd one with our 2019 120AH i3. Whether using a granny charger or our 7.2kw wall point, it's taking forever to charge - as long as 48 hours from 60 to 100%. I keep getting "Charge time increased" messages from the app - repeatedly during the same charging session, each one extending the time to full charge by hours. Interestingly, but possibly irrelevantly, the charge history in the app doesn't show all the sessions and none of the ones that are appearing record any charge actually passing to the vehicle (although it is, eventually, charging). The car otherwise works absolutely fine and shows no warnings or messages.
BMW want to charge £300 for diagnosis (it's out of warranty). Before I simply pony up, has anyone seen this? It's been going on for some time - it's not related to the recent freeze. I understand about things like charge scheduling and maximum charge rate - it's set for "charge immediately" and "maximum charging current 30A"; also we've made no changes to these settings since delivery and it has charged without issues on the same two chargers until a few months ago.
Both chargers happily charge our XC90 PHEV at the expected rate (granted that it can only accept 3.2kw, but the i3 is doing something like 0.35kw so that's not it).

Not sure if this is of any use but....has your car been to a BMW dealer for a service fairly recently?
Home charging on our i3 (2019 model) got a bit funky quite suddenly and we discovered that the charging settings had reverted to 'low'.
This unexpected charging behaviour occurred after the car came back from the dealer after its first service during which it got a 'standard scope' and may have included a software update. Presumably whatever happened during the update/standard scope changed the charging settings back to 'low'. As you probably know, changing the charging setting is pretty simple.
