Good day,I would just like to find out when did your car start misfiring? My bmw misfires when she is cold and throws the check engine light when I turn her off then she starts fine and then after a few minutes she misfires again and throws the check engine light again, once she is warmed up though she runs smooth so it only seems to be on cold starts, what symptoms were you getting?
At times my Bmw used do the same but it was intermittent and then we used to clear the codes off it used to last a few days then come back on also once mine was warmed up it used to misfire quiet bad, the symptoms I got was multiple misfire on nearly all cylinders so I replaced the lambda sensors as that what it showed on the diagnostic but turned out it was the Disa valve hope this helps

Also check your IAC just below the DISA.
What is the IAC ? And thank you for the information
