My software is up to date (car was serviced a few months ago). I have had it occur on a VERY cold day, at startup, that the gas motor fires up. I've also had that occur randomly, probably due to a certain # of key cycles that it does so to "check" things.

But I found that even if the gas motor fired up, it goes away after a bit. So it is probably something it does for checksum or similar. Remember, once the gas motor starts, it will not turn off few a little bit until it reaches optimal temps. Starting cold, it will stay on longer that first time until it shuts off.

If you park outside, and have a VERY short drive, the gas motor might come on/stay on for that direction. But if you park in a garage/car park, the gas motor should not fire up regularly unless you request, and the eMode should be 100% electric only.
