I'm unsure what this time period is, could be once every 30 seconds or every 30 minutes. I have no clue but it does state that in the manual.
In my owners manual the launch control instructions are wrong. I saw the correct way to do launch control on youtube videos. "Launch control on BMW M3 Frozen " is one the best youtube videos.
