Is this misfire? [16 sec video]
I bought 2007 E93 with the BMW performance exhaust. I don't think it needs a tune just for an exhaust but there is a pause in the exhaust sound during idle. The RPM moves a VERY little, almost unnoticeable.
Most notably between 9 and 14 seconds of the video |

Sounds like my car with my AA exhaust. Seems normal to me.
Edit: My car only does that once or twice during cold start up, once warm no problem. After watching video again it sounds like your car does it more often. Not so sure if normal now. |

328i_E92_2007 was correct. I ran a code scan and got 29CF (Cylinder 3 misfire) however this is only during a cold start and SEEMS to go away after the engine warms up as I can no longer feel or hear that noise. I don't know what to make of that

Sounds like mine before injectors were replaced on cold start
