@Glos Guy You’ve probably set off now, but press the button on the RH of the steering wheel with the 3 lines on it. This allows you to scroll through options of what appears in the driver display, one of which is Journey Data Meanwhile the usual BMW top button on the end of the indicator stalk moves through various journeys like since factory, since last charge, since start of journey and individual . A long press on the stalk button will reset the data. At least, this applies to my iDrive 8.5 version! Have fun!
Thanks for responding. Leaving soon. I found Journey Data but pressing and holding that selector on steering wheel isn’t resetting it. There is no button on the end of the indicator stalk ( mine has it and does the same as yours). Not impressed with OS9 so far. Way too complicated and not intuitive.
