All,
1st. he flap should be open before 1st start up so before you drive the car just go down and unplug the motor...no errors show.
2nd. I am switching mine back. It could be my imagination but it seems when I start to get on the gas below 2k the car resonates & vibrates a lil more Does anyone really know if the flap is an active tpe design or just off at start up and pen the rest of the time. I mean does it vary its position depending on RPM like possibly close up at lower rpms? Prolly just the way the MPE resonates but I will plug it back in this weekend and drive for a week to see if it is still there. I have not seen any advantage sound wise having it unplugged so I might go the route of the BMW engineers
