[Bimba_440i]

Hi. I have a 2020 440i gc M sport and I can’t get launch control to work. had since January. I’ve done the steps as written, Driven the 10 miles and waited for the engine to get warm. DSC off, Sport +, Shifter to S, brake All the way down, gas down to floor quickly pushing the resistance button. The car hunkers down, wheels don’t spin, but rpm only goes up to about 2500 and stays there, rises to about 2800. No flag comes up, and when I’ve “launched” that way the wheels don’t stop burning out until about 25mph. Anyone know what to do?

Help?
