Mein Auto: 09' 335i Sedan
Loso,

I just got an 09' 335i, and occasionally I was hearing the left exhaust on startup. The actuator which controls the butterfly valve was causing this and I simply disconnected the actuator from the trunk area so my valve is always open. Yet to hear the noise again.

You can search for "golf tee mod" and find a lot of results about this.
