The saga continues.
I'm curious about the number of instances where folks had this noise and actually had an engine failure. If I recall, the total number of folks who honestly had the same noise is pretty small, and, aside from an earlier member who mysteriously stopped posting after the engine was shipped to germany, there appear to have been relatively few actual bearing replacements and even fewer actual engine failures.
I was one of the first few to notice and post a video describing this problem. At the time I was unable to conjure the BMW dealership goodwill to get multiple replacement cars. But this ticking in my engine utterly disappeared, and I've been driving it without issue for the last 25000 miles. Curious.
