i3 Battery charging - Degradation real life experience

[alohart]

It's good to try something after you get the car - when I did six months after buying mine, I found that the dealer or previous owner had installed a GPS tracker in the OBD port!

A U.S. i3 would normally sound the alarm a while after it is shut down if an OBD dongle remains plugged in. I don't know how long after shutting down the alarm would sound. I participated in a state of Hawaii pilot program whose goal was to base the annual registration fee on the distance driven with maybe the vehicle's weight considered as well. An OBD dongle was used to transmit distance driven data via a cellular data connection to the DMV. The dongle set off the burglar alarm on our 2014 i3 sometime during the night. To prevent this, the value of the following coding parameter in the Roof Function Center (FZD) could be set to inactive:

OBD socket alarm (BimmerCode expert mode)
3002->OBD-Alarm: active (default)

However, setting this parameter to inactive is considered to increase the risk of an unknown OBD dongle being installed in one's i3. Maybe that change had been made to your i3 when the GPS tracker was installed.

Now that you mention it, I was getting spurious alarms, but perhaps that was related to super hot summer days. I have only tried BimmerLink so far but will try BimmerCode at some point in the next few months. In any case, no dongle installed now.

Same one I bought in the UK. Works well with the Electrified app, and also allowed me to code my car (with Bimmercode) when I changed the main screen up to a 10.25" unit.

I think that also means a new key can be coded on the steering column with suitable software/hardware via theOBD. Hence why it alarms if it detects current drain on the OBD port whilst armed. Was an issue in UK some time back with cloning kits. Required access to car via some other means usually blocking the locking request from the fob.

Either a wasp or current drain on OBD for sure.
