Make a video of the noise and open your hood.
The point to where you think the noise is coming from.
I will do the same, let's see if it is the same.
Ps: was told today by a highly reputable local Indy shop, to ad BG44R every 7500km to clean injectors.
Funny you me ruined that. Did a combo of oil change (I went from mobil 0w-40 to GC 0w-30) and techron injector cleaner a week ago and the car is sound!! My cars always seemed to be louder (this is my third 3 series) with mobil.. Not even sure why I used it again.
