Hi All,

My 2013 335xi (PWG) has some odd behavior after start-up and take-off when the car sits for a short amount of time. This normally doesn't happen after a cold-start or when the vehicle is still warm.

For example, it tends to happen every Wednesday night after I golf. Car is parked around 5pm and I leave around 8pm.

You can see in the chart that the pedal position remains fairly constant but the throttle and the RPMs dip and spike. After getting up to about 30mph it goes away and starts to act normal again.

The car has a JB4 (Map 1, but also happens with JB4 off), BMS Intake and Charge-Pipe. Does anyone have any idea what this could be?? Appreciate any help.
