Yep.. Just like Delta5 said.. I've had it happen twice to me in my 330i -- the second time this evening.

I rolled video on it so I had evidence of the problem, because for something intermittent, how am I going to get the dealer to acknowledge it?

I also have dropouts of CarPlay for 1/2 to 1 seconds fairly regularly -- but I am sure this isn't related.

The sound sounded like a ground wire came loose. You could hear it go up and down through revs of the engine as well.

I grow more and more frustrated with this car.
