Ok, so just to clarify the istep version has not been altered to my knowledge.
I have done some coding bits nothing major. But yeah I know bmw are more aware of things these days and will find any excuse to get out of stuff.
I use the car as a daily, it spends majority of its time in comfort or sport. It's only when I go for a weekend blast I'll flick it into sport plus. As this is the only drive mode the issue appears I'm not sure I could pinpoint how long it's been doing it for.
