ok, so my 2017 25i started this recently only on cold start and would sometimes stall. Local BMW dealer said no fault codes but hooked up diagnostics and sent data to BMW Australia. Fault was a fuel tank ventilation valve.. it was replaced under warranty. Cause is normally dirty fuel but have only ever put 98 octane from Shell. Maybe change to BP.

I also read there was a software update but not sure if it applied to the B48 engine..
