It has not made any difference to the DCQC and "Blue light" indicator - it still doesn't come on, and it also has not changed the battery rebalance point - it is still happening at 82% ... are both of these changes expected with that BMS update? Did they mess it up on me? Having the balance point move to 92% would help me a lot - as the weather gets colder, I use a DCQC 3-4 times a week, and being able to go up to at least 84% if not a bit higher, would be of tremendous help - I currently stop at 80% because it takes 3-4 minutes to move past the 81% point (around 95,000km)
It seems likely that you have not had the BMS upgrade - for me, the very common 82% balancing (just as you describe it) totally disappeared after the upgrade. Though, since then I have not seen any QC balancing at all, except for the very first time I had a 94% QC. Also, that time it was shorter than before, and happened at around 92%.
I'm not 100% sure that the blue light indications are related to the BMS upgrade itself; they are actually physically attached to the OBC, but the service guy didn't tell me anything about any upgrade of the OBC firmware. Still, the LED:s became active at that time.
To verify if the BMS software is updated, you could ask to get the battery report next time you have the car at service, and check the "cumulative operating time" or "cumulative energy charged" values. If the BMS was reset at last service, these values will be much too small.
