Re: Bent rims

Your local city/town might cover the cost if it was a known issue on that section of road?

Re: Cell balancing

I found some interesting information on https://www.newtis.info/tisv2/a/en/i01-i3-rex-hat/wiring-functional-info/power-train/high-voltage-battery-unit/1VnXGFKEDA : The SME regularly wakes up from its rest phases and compares all the cell voltages to one another. Since the adjustment of the cell vol...

Re: Battery capacity issue

If you have ISTA+ you can re-calibrate or re-initialize the HV battery. In the end the battery capacity does not change, it just changes or re-calibrates the GOM range and battery kappa values. Over time these values will not accurately reflect the actual battery capacity.

Re: 12v Battery Upgrade?

There is no exposure to high-voltage when changing the 12 V battery, so it's not a safety issue. However, if the high-voltage system is active when the 12 V battery is disconnected, the high-voltage system would suffer an unexpected shutdown which could cause problems. Opening the high-voltage disc...

Re: 12v Battery Upgrade?

When it says to disconnect the HV battery is that only for safety reasons or does it have something to do with protecting the computers?

Re: Range and AC usage

I wonder if the fact the car will cool the battery when it starts to go over a predetermined temperature is influencing the cabin temperature. I don't think the battery cooling circuit is separate from the cabin cooling circuit, so maybe if you deselect the A/C button, the cabin is still cooling bec...

Re: Unexpected, very powerful, acceleration surge BMW i3

I offered to exchange my 9 month old BMW for one of their used "service loaners" but they were not interested. And after suggesting various fair and reasonable exchange deals I noticed that they wouldn't budge, so I offered to exchange my BMW i3 for another BMW i3 but that move would ALSO result in...
